The mining levels that will get you the most diamonds are Y -59, Y -58, Y -57 and Y -56 (with -58 and -57 being the levels you're actually mining through, -59 being below you and -56 being above you). Normally, since -59 has the most diamond, we'd want to have it be one of our two inner levels, but Y -60 has so much less diamond that it is ...
Dopechess1. · 9m. my old 8 card gigabyte rx570 rig was doing 921watts at the wall @ 235mh/s. It was good efficiency in it's day. I rather optimize for efficiency vs pure hashrate. To me it's not worth it since my power is 17c/kw. btw.. i was able to get stable core at 1075/750mv core and 2050/775mv memory.
Highwall – The unexcavated face of exposed overburden and coal in a surface mine or in a face or bank on the uphill side of a contour mine excavation. Highwall miner – A highwall mining system consists of a remotely controlled continuous miner which extracts coal and conveys it via augers, belt or chain conveyors to the outside.
Other highwall mining apparatuses are disclosed in U.S. Pat. Nos. 5,112,111, 5,232,269, 5,261,729, and 5,364,171 to Addington et al. These patents show a highwall mining system that includes a self-propelled mining machine that is adapted to pull a series of interconnected cascading belt conveyors into the seam.
Highwall Miner. ( 1) ( 2) The machine is generally operated from a bench that is created by the removal of overburden material and coal by way of contour surface mining around the perimeter of a coal seam. Other highwall …

Highwall mining is an innovative technology that extracts coal with less expenditure and in a completely safe manner. Our Highwall Miners are unmanned cutters that are driven underground to a highwall of an exposed seam. The Highwall Miner makes cuts in the coal seam that then bring the coal back to the entry and pile it up.
Highwall mining: by many it's still considered on the fringes of being a viable, high production coal miner. But for those who know and use it, like contract miner Commonwealth Mining, it provides the safety standards and financial results that are helping grow their business and build their reputation.
Highwall mining is a primary method for mining coal from outcropping horizontal seams. In this method of mining, an unmanned continuous miner is driven underground and operated in front of the highwall. The highwall mining machine stands on the pit floor or on a bench, directly in front of the exposed seam and makes long parallel rectangular ...

Ergonomics Processes: Implementation Guide and Tools for the Mining Industry 2/1/2009 This paper describes how three mining companies partnered with the MSD Prevention Team at NIOSH to demonstrate that an ergonomics process could be systematically implemented and effectively integrated with existing safety and health programs.
A number of new tools for feasibility studies, including the Highwall Mining Index (HMI), the Auger Mining Index and Percentage Extraction estimate are presented in the report. The key components of this report include: Feasibility study. The geotechnical evaluation to determine whether the site is suitable for highwall mining.

production method, analysis shows that auger and highwall mining appears to be as safe as surface coal mining (6). However, there are geotechnical considerations with highwall mining that require careful engineering to realize the full economic and safe potential of highwall mining. Highwall stability is the overriding concern in highwall mining.
® Highwall Mining System The industry-leading highwall mining system is a new, low-cost addition to traditional mining methods. The system can produce 40 000-110 000 tonnes (44,000 to 121,000 tons) of coal per month, depending on seam height. Capable of full operation with a three- to four-man crew, the highwall mining system

Knowing a patient's height helps medical professionals make related observations about their health. An accurate measurement tool helps practices treat patients of all ages, from small children to older adults. Buying a stadiometer comes with many benefits for medical practices, hospitals, clinics and clinical research facilities.
Highwall Concerns. There are several geological hazards that are encountered during the life of a quarry or open pit mine. Most of these hazards are included in a mine's Ground Control Plan (GCP). The GCP ensures adequate geotechnical planning, safe mine operation and reclamation goals. Some measures of consideration in the GCP should include ...
High Wall Mining is a term applied to various approaches to removing coal and other desired materials in seams or veins under an overburden too deep to justify strip mining. The term is applicable where the appropriate machinery can be present in a cut or bench and extend a mechanism, including a conveyor and terminating with a cutter head or ...
The high wall mining system is capable of handling coal seam thickness from 26 to 16 ft with a dip up to 160. Low mining cost. Low labour requirement.
