Claims (4)
где с - сцепление в массиве горных пород;
β- произведение объемной массы пород
γ на коэффициент бокового давления, равный 0,5;
где ρ и ρ1- углы вертикального трения соответственно горных пород и податливого материала;
Н - глубина отработки полезного ископаемого;
d - эквивалентный диаметр рудного тела,
а обрушение горных пород осуществляют методом регулируемой поэтажной посадки подрабатываемого массива, ограниченного с флангов вертикальной отрезной щелью, под действием собственного веса, для чего скважины располагают так, чтобы последовательный их ввод в эксплуатацию, а соответственно и формирование общей компенсационной полости осуществлялись по спирали, при этом очередную скважину вводят в эксплуатацию при достижении кровлей предыдущей камеры предельных значений, предшествующих ее обрушению.A method of layer-by-layer mining of ore bodies by hydraulic mining, including opening the ore body with boreholes, forming a closed vertical cutting gap and filling it with malleable material, installing equipment in wells, disintegrating rocks, forming a compensation cavity, hydraulic erosion of minerals, delivering the resulting pulp to the surface and laying the mold displacement of production waste, characterized in that. that during the exploitation of deposits with a pillar-like form of the ore body, a vertical cutting gap closed along the contour of the ore body in the interval of its mining is formed from the surface to a depth determined by the formula
where c is the adhesion in the rock mass;
β- product of bulk mass of rocks
γ by a lateral pressure coefficient of 0.5;
where ρ and ρ 1 are the angles of vertical friction of rocks and ductile material, respectively;
H is the depth of mining;
d is the equivalent diameter of the ore body,
and the collapse of rocks is carried out by the method of adjustable floor landing of the undermined array, limited from the flanks by a vertical cutting slot, under the influence of its own weight, for which the wells are positioned so that their subsequent commissioning, and, accordingly, the formation of a common compensation cavity is carried out in a spiral, the next well is put into operation when the roof of the previous chamber reaches the limit values preceding its collapse.
