Description
II
Изобретение относитс к горной промышленности и предназначено дл управлени труднообрушаемой кровлей при pa3pa6otKe месторождений полез ных ископаемых подземным способом.The invention relates to the mining industry and is intended to control a hard-to-damage roof at pa3pa6otKe mineral deposits by the underground method.
Известен способ управлени труднообрушаемой кровлей 1 .There is a known method of controlling a roof that is hard to break.
Однако данный способ характеризуетс большим расходом воды, привод щим к увлажнению пород непосредственной кровли и ее разрушению.However, this method is characterized by a high consumption of water, leading to wetting of the rocks of the immediate roof and its destruction.
Известен способ управлени труднообрушаемой кровлей при разработке пластовых месторождений, включающий бурение скважин в основную кровлю пласта, зар жание, нагнетание воды, взрывание зар дов 2 .There is a known method of controlling a hard-to-collapse roof when developing reservoir fields, including drilling wells into the main roof of the formation, charging, injecting water, blasting charges 2.
Однако известный способ характеризуетс недостаточной эффективностью ..However, the known method is characterized by insufficient efficiency ..
Целью изобретени вл етс повышение эффективности за счет paiapyшени основной кровли и обеспечени регулируемого разрушени пород.The aim of the invention is to increase the efficiency due to the paiapy of the main roof and to ensure the controlled destruction of the rocks.
Поставленна цель достигаетс тем, что после взрывани дополнительно нагнетают воду и в ней создают импульсы высокого давлени .This goal is achieved by the fact that, after the explosion, water is additionally injected and high pressure pulses are created in it.
На фиг. 1 изображена схема расположени скважин в выемочном поле; на фиг. 2 - расположение скважин в породах основной кровли.FIG. 1 shows the layout of wells in the excavation field; in fig. 2 - the location of wells in the rocks of the main roof.
Способ осуществл етс следующим образом.The method is carried out as follows.
