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.

Claims (2)

С конвейерного 1 или вентил ционного 2 штрека в основную кровлю 3 бур т скважину 4, зар жают ее и взрывают . В качестве забойки скважин перед взрыванием примен етс  вода. Посts ле взрывани  скважину подсоедин ют к гидроимпульсной установке 5. через которую дополнительно нагнетают воду и с помощью гидроимпульсной установки создают в ней импульсы вы20 сокого давлени . В результате гидроимпульсного воздействи  происходит разрушение пород основной кровли, увеличение радиуса трещин при минимальмом расходе жидкости, подаваемой в горный массив. Предлагаемый способ позволит значительно повысить эффективность управлени  трудиообрушаемой кровлей. Формула изобретени  Способ управлени  труднообрушаемои кровлей при разработке пластовых месторождений, включающий бурение скважин в основную кровлю пласта , зар жание, нагнетание воды, взрывание зар дов, отличаю92 04 щ и и с   тем, что, с целью повышени  эффективности за счет разрушени  основной кровли и обеспечени  , регулируемого разрушени  пород, после взрывани  дополнительно нагнетают воду и в ней создают импульсы высокого давлени . Источники информации, прин тые во внимание при экспертизе 1. Авторское свидетельство СССР ff , кл. Е 21 С 41/OU, 1972. From conveyor 1 or ventilating 2 drift into the main roof 3 bore a well 4, charge it and blow it up. Water is used as a downhole before blasting. After detonation, the well is connected to the hydro-pulse installation 5. Through which water is additionally injected and with the help of the hydraulic-pulse installation, high-pressure pulses are generated in it. As a result of the hydroimpulse effect, the rocks of the main roof are destroyed, the radius of the cracks increases with the minimum flow rate of the fluid supplied to the mountain massif. The proposed method will significantly improve the management efficiency of the roof to be scraped. The invention The method of managing a hard-to-collapse roof in the development of reservoir fields, including drilling wells into the main roof of the reservoir, charging, water injection, explosive charges, differs 92 04 u and in order to increase efficiency by destroying the main roof and providing controlled destruction of rocks, after blasting, additional water is injected and high pressure pulses are created in it.
