Cut and fill - QueensMineDesignWiki

Selection ConsiderationsPlanningDevelopmentBackfill RequirementsCosting InformationInfrastructure RequirementsReferencesThere are a number of ore body features that should be considered when evaluating the applicability of a cut and fill mining technique. These features include:• Orebody geometry• Ore grade/method cost• Rock quality• Waste Disposal The ore body must be narrow and steeply dipping as the method relies on gravity to draw ore. Cut and fill is a very expensive mining method, due in large part to the high costs of backfill. This cost c在minewiki.engineering.queensu.ca上查看更多信息

Types of Underground Mining Method Comparison

Rill-Cut Stoping Mining. Rill cut, or rill stoping, as shown at B, Fig. 2, has the principal advantage that when filling is used it can be run down through a raise at the apex of the stope and will fill the stope without shoveling. Its disadvantages, on the other hand, are as follows:

Underhand Cut and Fill Mining as Practiced in Three Deep ...

Galena Mine with the introduction of mechanized underhand cut and fill mining. The goal was to recover ore beneath the lowest level of the mine in an area where rockbursts had occurred and ground conditions were very poor. The initial stope was mined using the underhand method from the 5,500 level downward on a 70 o dipping vein.

Planning StepsDevelopment of InfrastructureMining ProcessStope Development and AccessProductivityEquipmentMaterial HandlingDrillingBlastingGround SupportSafetyThe first characteristics to evaluate are the size, dip and plunge of the orebody, which is important because the installations of draw points are essential to the gravity flow of the blasted ore for collection. The second element to assess is the shape and consistency of the orebody. Two horizontal drifts are required before mining can take place, which are to have a very large vertical separation. The distance between the two drifts depends on the consistency of the ore, the drilling accura...

Narrow vein minimum dilution case study – AMC Consultants

Vein CharacterizationOptimized Dilution ScenariosFormulaeBenchmarking and Case StudiesEquipmentOptimized Stope and Drive DilutionCase Study Guidelines and Processes to Reduce DilutionThe dilution study began with vein characterization. The broad aim was to identify the general variability in vein width, geometry, and lateral extent (strike and dip) and, as far as practicable, to identify geotechnical conditions that may determine the applicability of various mining methods. The findings included: 1. Consistent vein strike 1,500 m. 2. Vein width ranging from 0.5 m to more than 5 m. 3. Ground condition ranging from poor to good, across strike and depth extents. 4. Cemented...

Mining - Blasthole stoping Britannica

Mining - Mining - Blasthole stoping: When the dip of a deposit is steep (greater than about 55°), ore and waste strong, ore boundaries regular, and the deposit relatively thick, a system called blasthole stoping is used. A drift is driven along the bottom of the ore body, and this is eventually enlarged into the shape of a trough. At the end of the trough, a raise is driven to the drilling ...

Lucky Friday Mine - QueensMineDesignWiki

Mining Method Overview. Lucky Friday used a conventional stoping cycle that consisted of sampling, drilling, blasting, mucking, rockway for extraction, backfilling, loading and hauling, ground support, and stope ventilation.The reason cut and fill was chosen is because the slusher was the most efficient mucking technique for a narrow, steeply dipping orebody where high selectivity is essential.

Currently, approximately 60% of the gold comes from the Hoyle Pond underground mine, where mechanized cut and fill and longhole mining methods are used to extract the ore, and the remaining ore comes from the Hollinger Open Pit mine.

Copperstone Mine - Mining Intelligence and News

The mining method proposed for the Copperstone Project is a mechanized cut and fill using Cemented Rock Fil (CRF). Cut and fill was chosen for its flexibility in effectively mining low vein dip angles. The method also minimizes the amount of dilution during mining by careful geological and management control of the mining.
