New Quarry Manegement Course: Full Course & Training Guide

The new quarry management course is the modern formation of the quarry professional: in the past the quarry was the stepchild of the cement plant, the dusty pit where the stone came from: today the quarry is the strategic resource: its chemistry, its yield, its equipment, its safety and its rehabilitation decide the cost sheet and the license to operate of the whole cement company: the course of the package is the complete curriculum of the modern quarry: from the geology to the pit plan, from the drilling to the blasting, from the crushers to the environmental closure.

The Complete Cement Technical Package (931 files including the books, the courses, the Excel tools and the presentations: $249.99 one-time: instant download via the PayPal payment) includes this quarry management course with its lectures, its case studies, its calculation sheets and its register templates: the formation covers the exploration, the planning, the extraction, the safety and the regulations: this article walks the entire course module by module: the reader acquires the vocabulary and the methodology of the modern quarry manager.

This page takes the same order as the course: the geological map first, the exploration and the reserves second, the mine plan third, the drilling and the blasting fourth, the loading and the transport fifth, the environment and the safety sixth, and the management and the economics last: the numbering of the sections matches the modules of the course: the reader can follow the file with the article beside it: the promise: after this page, the reader sees the quarry with the eyes of a manager, not only with the eyes of a visitor.

1. The Geological Basis of the Quarry: The Rocks that Feed the Cement

Every cement deposit has its story in the geology: the limestone formations of the Cretaceous and the Jurassic hold most of the world’s cement raw materials: the course begins with the geological reading of the deposit:

• The limestone families: the hard compact limestone, the chalk and the marl: the calcite content, the clay content and the hard streaks: the cement quality starts at the geology: the CaCO3 of the limestone above 75 percent for the normal plants:
• The Argillaceous component: the clay, the marl and the shales: the silica, the alumina and the iron of the raw mix: the quarry pairs the calcareous and the argillaceous: the balance of the two:
• The corrective materials: the sand, the iron ore and the bauxite: the small quarries and the purchased supplements: the correction of the chemistry of the main stone:
• The structures: the faults, the joints, the karst cavities and the clay pockets: the sudden changes of the deposit quality: the geological map of the plant: the drilling plan of the study:
• The overburden: the soil and the weathered rock above the economic layer: the stripping ratio: the cubic meters of the removed per tonne of the stone: the cost driver of the open pit:

The geological course of the file presents the base maps, the sections and the structural features with the photographs and the legends: the quarry geologist and the manager read the deposit like a book: the pages are the strata and the words are the chemistries: the file turns the science into the working knowledge of the plant: the first week of the course: the geology.

2. The Exploration and the Estimation of the Reserves

The quarry exists only after the exploration proves it: the estimation of the reserves is the bank statement of the quarry: the file takes the student through the complete exploration campaign:

• The mapping: the geological maps of the area, the satellite imagery and the previous borings: the office stage of the exploration: the plan of the drill holes:
• The drilling: the core drilling and the percussion: the grid of the holes of 100 x 100 m down to 50 x 50 for the details: each hole the sample of the strata:
• The sampling: the core logging: the density, the recovery, the chemistry of the meter-by-meter samples: the XRF of the laboratory: the moisture and the physical tests:
• The reserve classification: the measured, the indicated and the inferred: the confidence levels: the standards of the reporting: the bankable documents of the investors:
• The economic analysis: the mineable tonnes and the life of the quarry: the recoverable at the plant gate: the cost of the exploration per tonne of the reserve: the investment case:

The estimation of the reserves is the arithmetic of the future: a cement plant of 5,000 t/d consumes about 1.5 to 2 million tonnes of the raw material each year: the quarry life of 30-50 years asks for the reserves of 50-100 million tonnes of the extractable stone: the file calculates the complete case in its worked example: the reader finishes the module able to evaluate any deposit: the reserve certificate of the quarry: the profession of the exploration.

Reserve class	Confidence	Drilling density	Use
Measured	high	50 – 100 m grid	mine plan, design
Indicated	medium	100 – 200 m grid	investment
Inferred	low	200 – 400 m grid	long range plan

The course of the file completes the module with the statistical treatment of the grades: the mean, the variance and the variogram of the deposit: the block model of the modern tools: the student of the course performs the reserves estimation on the case of the file with the Excel templates: the reality check of the module: the money of the reserves is the money of the mine.

3. The Quarry Planning: From the Block Model to the Pit Design

The mine plan is the blue book of the extraction: it says exactly where the stone comes from in the next year, the next five years and the next thirty: the course teaches the planning methodology of the modern quarry:

• The block model: the deposit divided into the blocks of known chemistry and tonnage: the three-dimensional model of the pit: the statistical engine of every plan:
• The pit design: the benches, the benches height of 10-20 m, the slope angles and the pit bottom: the safety berms and the access ramps: the geometry of the extraction:
• The sequences: the year plans by the bench: the chemistry smoothing from the alternating layers: the blending of the good and the poor stone in the sequence: the kiln feed quality in the plan:
• The relocation planning: the plant moves through the pit: the crusher relocates every years: the conveyor extensions and the road moves: the sequence is the living cost of the quarry:
• The software and the spreadsheets: the planning tools of the industry and the Excel planning templates of the package: the schedule of the benches and the grades: the optimization of the sequence:

The plan of the file: the 10-year production schedule with the monthly detail: the chemistry envelopes of every year and the blending strategies: the quality rejections of the plan: the contingencies for the weather and the equipment: the course gives the complete examples: the student builds the plan of his plant with the worksheet: the result: the quarry runs five years ahead of its own future instead of six months behind the kiln demand.

4. The Drill and the Blast: The First Fragmentation

The drilling and the blasting free the stone from the mass: the blasting design decides the fragment size, the slope stability and the safety of the surrounding: the module of the file is the complete blasting formation of the blasting certificate level:

• The drill rigs: the rotary and the percussion drills: the hole diameters 89-141 mm of the bench blasting: the drilling pattern of the grid: the meters drilled per tonne: the cost of the drilling:
• The explosives: the ANFO and the emulsions: the densities and the strengths: the initiation systems: the electric and the electronic detonators: the delays of the initiating pattern:
• The blast design: the burden, the spacing, the stemming and the sub-drill: the powder factor kg of the explosive per tonne: the fragmentation goal: the rules of the file: the tables of the burden per the hole:
• The environmental effects: the vibration at the distance, the air blast and the flying rock: the limits of the neighbors: the blast monitoring with the seismographs: the records of every blast:
• The safety of the blast: the exclusion zone, the initiation procedure, the misfire handling and the post-blast inspection: the strict operation of the file: the certification of the blasted area:

The blasting practice of the course: the complete design of the working blasts with the numbers: the burden 2 m for the 89 mm hole, the spacing 2.5-3 m, the stemming 3 m: the powder factor of the limestone 0.15-0.4 kg/t: the course gives the calculation tables and the records: the blasting is the hourly economics: the fragment too coarse robs the crusher capacity, the fines waste the energy: the discipline of the design and the monitoring: the champion module of the quarry course.

The blast design tables of the file deserve the attention: for the bench height of 15 m and the hole diameter of 115 mm the typical pattern of the file is the burden 3.0-3.5 m and the spacing 3.5-4.0 m, with the sub-drill of 1-1.5 m below the bench level and the stemming of 3-4 m: the initiation sequence with the row delays of 25-50 milliseconds produces the free face breakage: the fragmentation control is the audit: the sieve analysis of the muck pile and the loader cycle in the following hours: the good blast and the bad blast are measured by the crusher throughput: the file carries the fragmentation estimation curves and the cost comparison of the trial blasts: the student of the course performs his own pattern design against the case rock and defends the choice with the numbers: the second nature of the trained blaster.

The weather changes the blasting day: the wet holes of the rainy season need the waterproof emulsion instead of the ANFO: the cold seasons the sensitivity of the initiating systems: the static and the stray currents at the pit: the grounding of the initiation network of the electric detonators replaced by the electronic caps immune to the interference: the course explains the modern initiation: the electronic detonators with the individual programming: the millisecond precision of the pattern, the reduction of the vibration and the fly rock: the electronic initiation has become the standard of the modern quarry and the file covers the systems, the programming and the legal certification of the operators: the complete electrical initiation.

5. The Loading, the Haulage and the Crusher Feeding

Between the blasted pile and the primary crusher stands the loading and the hauling fleet: the cycle of the trucks and the shovels is the throughput machine of the quarry: the module studies the fleet economics:

• The loading equipment: the hydraulic shovels, the wheel loaders and the backhoes: the bucket size against the truck: the number of the passes: the 4-6 bucket loads per the truck standard:
• The haul trucks: the rigid dump trucks of the 40-100 t and the articulated: the cycle time, the speed curves and the grade resistances: the payload and the availability of the fleet:
• The match factor: the truck capacity against the loading rate: the idling of the trucks at the shovel: the queue of the plant: the fleet matching calculation of the file: the minimization of the waste:
• The in-pit crusher solution: the crushing inside the pit with the conveyor to the plant: the elimination of the truck cycle: the economics of the big pits: the case of the file:

The load is the loader-truck-crusher: the heartbeat of the quarry: the file shows the calculations of the fleet: the 4 trucks per the 250 t/h: the cycle of 12-15 minutes: the utilization of the 85 percent: the team learns to size and to balance the fleet with the spreadsheets: the pits of the world run the same discipline and the best plants run the same numbers: the module: the transport economics of the quarry.

The haul road is the forgotten civil asset of the pit: the road of the 25-30 m width, the 8-10 percent maximum grade, the crowned surface and the drainage beside it: the good haul road saves the 10-20 percent of the cycle time against the neglected one: the course includes the road design chapter: the curves of the road, the intersections and the pull-up areas of the crusher feed: the grader passes daily and the water truck keeps the dust down: the tires of the trucks last twice on the smooth bed: the file gives the road maintenance schedule: the grader hours per week and the base renewals: the road is the first investment of the pit that pays the second year: the attention of the manager.

The winter and the night operation close the module: the lighting of the quarry floor, the mirrors and the cameras, the visibility rules of the dark shift: the slippery ramps after the rain and the ice: the seasonal operation plan with the reduced shift hours of the fog: the high risk moments identified: the file includes the night operation checklist: the quarry security: the operating discipline of the 24-hour pits: the course: the complete operator knowledge.

10. The Frequently Asked Questions About the Quarry Management

How many years of reserve should the cement plant have?

The industry targets the 30-50 years of the extractable reserve: the banks and the investors expect the life beyond the depreciation: the renewal of the permit and the expansion of the lease: the reserves of the file: the mining plan of the plant is drawn against the full life.

What is the powder factor of the blasting?

The powder factor is the kilograms of the explosive per tonne of the blasted rock: the 0.15-0.40 kg/t for the limestone of the cement industry, the exact value by the rock hardness and the desired fragmentation: the blasting module of the course teaches the design and the monitoring of the factor.

What is the difference between the measured and the indicated reserves?

The measured reserve has the high confidence of the dense drilling (the 50-100 m grid) and can support the detailed design: the indicated comes from the wider drilling and supports the investment decisions: the classification follows the standards of the reporting: the table of the course: the confidence of the numbers.

Can the quarry operate in the rainy season?

The pits of the rainy climates manage the water: the sumps, the dewatering pumps, the haul road covers: the plan of the extraction avoids the flooded benches: the moisture management of the feed and the clay behavior: the seasonal plan of the quarrying course
