  • Patent number: 4222612
    Abstract: The method of mining flat-dipping and sloping beds of a mineral with hydraulic excavation which includes dividing the bed being mined into levels and sublevels. The height of the sublevels is determined by the rock geology of the bed formation. The sublevels, in their turn, are subdivided into blocks, the width of each block being short of the limit length of the steady or self-supporting outreach of the cantilever of the rock of the main roof with the given pattern of cutting into the bed with the cutting drifts and holes defining the short working faces. The spacing of the blocks being worked in the upper and lower sublevels in the direction of strata is set to preclude inter-influence of the bearing rock pressure in the blocks where the stoping work is being done. The method enables the conduction of a stable excavation of the mineral over an extended front of stoping.

  • Patent number: 4199192
    Abstract: In the method of mining mineral deposits with hydraulic extraction a seam to be mined is divided into long pillars along the strike, and each pillar is subdivided with extraction workings and breakthroughs into benches defining short working faces, whereafter a single hydromonitor mounted in an extraction working is operated for stoping in the two adjacent benches, in the direction of the gravity flow of the slurry therealong. In accordance with the invention, boundary or run-around entries are driven, and communicated with the extraction workings via cut breakthroughs, whereafter these cut breakthroughs are expanded up to the sole of the seam, whereby at the stoping of the extraction cut in the two adjacent benches in the direction of the sloping of the extraction and boundary entries the main stream of the slurry is removed from the stope through the boundary working.
