Description

Изобретение относитс к горной промышленности и может быть использовано нри скважинной разработке угольных пластов.The invention relates to the mining industry and can be used in downhole mining of coal seams.
Известен способ скважинной разработки угольных пластов, включающий вые.мку угл полосами по падению посредством скважинн 1х гидромониторов с оставление.м целиков угл I.There is a method of borehole development of coal seams, which includes outcrop of coal stripes in the fall by means of borehole 1x jetting machines with leaving m pillars of coal I.
Однако даннЬ)1Й способ характеризуетс потер ми и разубоживанием угл из-за невозможн () четкого оконтуривани целиков .However, this method is characterized by the loss and dilution of the coal due to the impossible () clear contouring of the pillars.
Известен также способ скважинной разработки угольных пластов, включающий гидроотбойку угл заходками полоса.ми по падению из скважин с остав.пением ленточных целиков уг. 2|.There is also known a method of borehole development of coal seams, which includes hydrofining of coal by striking stripes in the direction of a fall from wells with remaining coal pillars. 2 |.
Однако такой способ имеет, ограниченную область применени и не может быть использован нри разработке пластов со слабыми вмещаюншми породами, кроме того, он характеризуетс недостаточной надежностью разраооткн.However, this method has a limited scope and can not be used in the development of reservoirs with weak host rocks, in addition, it is characterized by a lack of reliability.
Цел1зЮ изобретени вл етс расширение области применени скважинной разработки и повьниспие LV надежности.The purpose of the invention is to expand the field of application of downhole development and to increase LV reliability.

Это достигаетс тем, что отработку ведут спаренными полосами с оставлением ленточных целиков между смежными парами полос и гидроотбойкой спаренных полос из скважин , расположенных в каждой из спаренных полос со стороны ленточного целика, причем гидроотбойку заходок спаренных по,пос осуществл ют во встречном направлении, а в выработанном пространстве каждой из полос между заходками остам ют целики угл , придава им наклон в сторону скважн {, предотвращающий сползание обрущенных пород кровли из отработанных заходок отрабатываемой и отработанно полое в отрабатываемую заходку.This is achieved by working out paired strips, leaving tape pillars between adjacent pairs of strips and hydrofixing paired strips from wells located in each of the paired strips from the side of the ribbon pillar, and the developed space of each of the lanes between the inlets remains on the pillars of the coal, giving them a slope in the direction of the well {, which prevents the collapsed roof rocks from slipping out of the worked-in approaches and Worked hollow in workable entry.
На чертеже дана схема ведени очистных работ.The drawing is a cleanup management scheme.
Способ заключаетс в следующем.The method is as follows.
Дл подготовки участка провод т штреки 1 и 2. Полосу 3 отрабатывают из скважины 4, а иолосу 5 -- пз скважины 6. Спаренные полосы 3 и 5 отрабатывают последовательно по падегщю. Заходки 7 н 8 спаренных полос вынимают во встречном направлении. В вь работанном пространстве каждой из полос между заходками оставл Drifts 1 and 2 were made to prepare the site. Band 3 was worked out from well 4, and Volos 5 - made from well 6. Paired bands 3 and 5 were worked out successively. Sunset 7 n 8 paired bands are removed in the opposite direction. In the working space of each of the lanes between the entries,
