Description

Изобретение относитс  к горной промышленности и может быть использовано при разработке пологих угольных пластов дл  управлени  кровлей.The invention relates to the mining industry and can be used in the development of flat coal seams for roof control.

Известен способ управлени  кровлейThe known method of controlling the roof

при разработке пологих угольных пластов, включающий бурение скважин в основную кровлю пласта из выработок, пройденных по вышележащему пласту, зар жани  указанных скважин и их взрьшание l. Однако данный способ имеет ограниченную область применени  и может, быть осуществлен только при разработке сближенных пластов,in the development of flat coal seams, including the drilling of wells into the main roof of the reservoir from the workings that have been traversed along the overlying reservoir, the charging of these wells and their drilling. However, this method has a limited scope and can only be implemented in the development of contiguous layers

Известен также способ управлени  труднообрушаемой кровлей при разработке пологих угольных пластов длинными очистными забо ми, включающий бурение скважин в кровлю пласта из выработки и создание сплошной разгрузочной щели в кровле пласта путем взрывани  указанных скважин . Однако данный способ недостаточно эффективен в определенных горно-геологических услови х.There is also known a method for controlling a hard-to-collapse roof when developing flat coal seams with long cleaning holes, which includes drilling wells into the roof of the formation from production and creating a continuous discharge gap in the roof of the formation by blasting these wells. However, this method is not effective enough in certain geological conditions.

.Целью изобретени   вл етс  повышение эффективности управлени  труднообрушаег мой кровлей.The object of the invention is to increase the efficiency of managing a hard-to-damage roof.

Цель достигаетс  тем, что скважины бур т на высоту не менее 1/3 труднообрушаемой кровли из бутовой выработки, проводимой вслед за подвиганием очистного забо  параллельно откаточной выработке , причем линию груди забо  располагают диагонально по отношению к выработкам с образованием острого у1|ла между линией груди забо  и направлением откаточной выработки со стороны выработанного пространства.The goal is achieved by the fact that the wells are drilled to a height of not less than 1/3 of the hard-to-collapse roof from the quarry excavation, following the advancement of the refinery slab parallel to the haulage excavation, the bottom line of the breast slab diagonally in relation to the mines with the formation of a sharp wedge between the chest line the slaughter and direction of the haulage from the side of the goaf.

На фиг. 1 представлена схема осуществлени  описываемого способа; на фиг, 2 то же, разрез по А-А на фиг, 1,FIG. 1 shows a scheme for carrying out the described method; FIG. 2 is the same, section along A-A in FIG. 1,

Пологий угольный пласт 1 отрабатывают длинным очистным забоем с предварительным проведением откаточной и вентил ционной выработок 2 и 3, Вслед за подвиганием очистного забо  параллельно откаточной выработке провод т б.утовую выработку 4, из которой в кровлю пласта бур т скважины 5 на высоту не менееThe flat coal seam 1 is worked by a long clearing face with preliminary carrying out haulage and ventilation workings 2 and 3. Following the advancement of the clearing face parallel to the haulage development, the bore production 4 is carried out, from which a well 5 is drilled to the roof top at least
