Abstract
Изобретение относитс к горному делу и позвол ет повысить безопасность горных работ. Угольный пласт 1 разрабатывают над или под целиком (Ц) 2. По мере отработки угольного пласта определ ют границу 3 вли ни Ц на разрабатываемый пласт. При подходе очистного забо к указанной границе определ ют участки 4 максимальных напр жений, действующих на Ц. Затем из подготовительных выработок бур т скважины 5 в Ц. Перебуривают ими Ц на участках действи максимальных напр жений. Зар жают скважины патронами ВВ и взрывают их. В разупрочненный Ц нагнетают жидкость в режиме высоконапорного увлажнени и полностью его разрушают. 1 ил.The invention relates to mining and improves mining safety. Coal seam 1 is developed above or below the whole (C) 2. As the coal seam progresses, boundary 3 of the influence of C on the seam under development is determined. At the approach of the clearing intake to the specified boundary, the sections of 4 maximum stresses acting on the C are determined. Then, from preparatory workings, wells 5 are drilled in the C. The wells are charged with explosives and exploded. In the softened C, the liquid is injected in the mode of high-pressure moistening and completely destroys it. 1 il.
Description
Изобретение относится к горной промышленности и может быть использовано при разработке свит пластов полезных ископаемых.The invention relates to the mining industry and can be used in the development of suites of mineral strata.
Целью изобретения является повыше- 5 нйе безопасности горных работ.The aim of the invention is to increase the safety of mining operations.
На чертеже показана схема разгрузки подрабатываемого целика.The drawing shows a scheme for unloading an underworked pillar.
Способ осуществляют следующим образом.The method is as follows.
При подходе очистного забоя угольного пласта 1, разрабатываемого под целиком 2, к распределение напряжений, действующих Hit целик. Выявляют участки 4 действия максимальных напряжений Кмакс в целике. Затем бурят скважины 5. Перебуривают ими лик на участках действия максимальных пряжений, доставляют в целик патроны границе 3 влияния целика определяют це. на I В В и производят их взрывание.With the approach of the face of coal seam 1, developed under whole 2, to the distribution of stresses acting Hit entirely. 4 plots reveal action maximum stress ma kc K in its entirety. Then, boreholes are drilled. 5. They drill the face in the areas of maximum yarn action, deliver cartridges to the rear of the border 3, the influence of the pillar is determined. on I In In and produce their blasting.
Затем нагнетают в разупрочненный цеΙΚ жидкость в режиме высоконапорного увлажнения и разрушают его полностью. Все операции по разрушению угольного целика производят в момент, когда на него действуют максимально возможные в конли кретных горных условиях нагрузки и горное давление играет дополнительную положительную роль для его разрушения.Then, they are injected into a softened fluid in the high-pressure humidification mode and completely destroy it. All operations on the destruction of a coal pillar are carried out at a time when the maximum possible loads in specific mountain conditions act on it and rock pressure plays an additional positive role for its destruction.
