the Moranbah North coal mine, it targets the same Gonyella Middle coal seam as the Moranbah mine, and it is expected to produce five million tonnes of coal per annum from its underground long wall operation over the next 26 years. The Grosvenor Coal Mine has a planned expansion in which two decline tunnels will be required for
Shaft mining or shaft sinking is excavating a vertical or nearvertical tunnel from the top down, where there is initially no access to the bottom.. Shallow shafts, typically sunk for civil engineering projects differ greatly in execution method from deep shafts, typically sunk for mining the top of the excavation is the ground surface, it is referred to as a shaft; when the top ...
Mine Design Relating to Dimensions and Shape. The aim of this aspect of strata control is to make the strata self supporting as far as possible, or if not, to minimize the extra support work required.
Although the fundamental premises underlying the choice of mine dewatering design are the same for all mines, experience on Southern Africa Mines has shown that there are differences between the designs adopted by gold, coal and diamond mines. These are primarily in the areas of approach, methodology, design and application. The major
The project included a numerical assessment of the probable hydrologic consequences for surface resources resulting from the mine''s expansion. At an open pit coal mine in the Powder River Basin, Wyoming, the problem was too little drainage of water from the channel and crevassesplay sands and overbank mudstones, which lie over the coal seams.

Design of Surface Mine Haulage Roads – A Manual By Walter W. Kaufman and James C. Ault ABSTRACT This Bureau of Mines manual for design of surface mine haulage roads covers such aspects of haulage road design as road alignment (both vertical and horizontal), construction materials, cross slope, and drainage provisions.
Jan 16, 2018· The NIOSH Mining Program has developed guidelines and criteria for the design of longwall gateroad pillars and coal and limestone pillars used in retreat mining. These guidelines are to a large extent empirically derived and based on case histories of pillar performance from a number of mines.
