Изобретение относитс к горной промышленности и может быть использовано при разработке пологих и наклонных сближенных угольных пластовThe invention relates to the mining industry and can be used in the development of flat and inclined contiguous coal seams.
Известен способ разработки пологих и наклонных сближенных угольных пластов, включающий совместную подгтовку пластов и их последующую отработку l3 .There is a method of developing flat and inclined contiguous coal seams, including joint podgtovka layers and their subsequent testing of l3.
Известен также способ разработки пологих и наклонных сближенных уголных пластов подэтажами, включающий проведение подготовительных выработок и отработку подэтажей в нисход щем пор дке длинными очистными забоми по простиранию 2Д .There is also known a method of developing flat and inclined contiguous corner seams in sub-floors, including carrying out preparatory workings and working out sub-floors in a descending order by long clearing areas along the 2D stroke.
Однако оба указанных способа характеризуютс значительным объемом родго.товительных работ, а также недостаточной эффективностью.However, both of these methods are characterized by a significant amount of labor-producing works, as well as a lack of efficiency.
Цель изобретени - уменьшение объема подготовительных работ и повьинение эффективности разработки.The purpose of the invention is to reduce the amount of preparatory work and improve the efficiency of development.
Поставленна цель достигаетс тем, что при отработке верхнего пласта четного подэтажа производ т отработку нижнего пласта.смежного нечетного подэтажа, а при отработке нижнего пласта четного подэтажа отр абатывёиат верхний пласт нечетного подэтажа, отсто щего от четного подэтажа, в котором отрабатывают нижний пласт, на два подэтажа, при- чем при отработке верхнего пласта каждого нечетного подэтажа вслед за подвиганием очистного забо провод т подготовительные выработки по нижнему пласту этого подэтажа.The goal is achieved by working out the upper stratum of an even substep downlining the lower stratum of the adjacent odd substage, and when practicing the lower stratum of an even subsubtrade, the upper stratum of the odd stratum from the even substage, in which the lower stratum of the lower stratum, is worked out substage, moreover, during the development of the upper stratum of each odd subsurface, following the advancement of the clearing bed, preparatory workings are made along the lower stratum of this substage.
На фиг.1 и 2 представлены схемы Figure 1 and 2 presents the scheme
O последовательной отработки пластов.O sequential mining of layers.
Способ осуществл етс следующим образом.The method is carried out as follows.
При отработке пологих и наклонных сближенных угольных пластов в процессе отработки верхнего пласта четного подэтажа 1 длинными очистными забо ми по простиранию производ т отработку нижнего пласта смежного нечетного подэтажа 2. При отработке When mining flat and sloping near coal seams, in the process of mining the upper seam of even substage 1 by long clearing strikes along the strike, the lower seam of adjacent odd substage 2 is tested.
0 . нижнего пласта четного подэтажа 1 отрабатывают верхний пласт нечетного подэтажа, отсто5пцего от четного подэтажа, в котором отрабаты вают нижний пласт, на два подэтажа. Подэтажи отрабатывают в нисход щем пор дке. При выемке верхнего пласта каждого нечетного подэтажа 2 вслед за подвиганием очистного забо 3 провод т подготовительные выработки 0 the lower stratum of even substage 1 is worked out by the upper stratum of odd substage, which is separated from the even substage in which the lower stratum is worked out, into two subsubjects. Sub-floors are worked out in descending order. During the excavation of the upper layer of each odd sub-floor 2, following the advance of the refining hole 3, preparatory workings are made
0 4 и 5 по нижнему пласту этого под,этажа . Полготовительные выработки, оконтуриваквдие выемочные столбы, используютс повторно при отработке Смежных столбов. Верхний пласт в каждом нечетном подэтаже отрабатывают по сплошной системе, а нижний пласт - по столбовой. Верхний и нижний пласт в четных подэтажах отрабатывают по столбовой системе с использованием выработок смежных столбов.0 4 and 5 on the lower layer of this under, floor. The preparatory workings, the contouring of the excavation pillars, are reused when working on the Adjacent pillars. The upper layer in each odd substage is worked out in a continuous system, and the lower layer in a pillar one. The upper and lower layers in even sub-floors are worked out by a pillar system using the workings of adjacent pillars.
Предлагаемый способ позвол ет уменьшить объем подготовительных работ и повысить эффективность разработки .The proposed method allows to reduce the amount of preparatory work and improve development efficiency.
