Description

Изобретение относится к горной промышленности и предназначено для разработки пологих угольных пластов.The invention relates to the mining industry and is intended for the development of flat coal seams.

Цель изобретения — повышение эффективности разработки путем использования энергии опорного давления.The purpose of the invention is to increase the efficiency of development by using the energy of the reference pressure.

Способ осуществляется следующим образом.The method is as follows.

Выемочный столб подготавливают путем проведения по простиранию пласта транспортного штрека и вентиляционного штрека. 10 После подготовки столба приступают к его отработке длинным очистным забоем. Линию последнего располагают перпендикулярно к штрекам. Выемку угля производят путем нанесения вертикальных щелевых разрезов в забое по нормали к пласту одновременно по всей длине лавы глубиной, равной 1/2 мощности пласта, расположенных на расстоянии Ь один от другого, определяемом из выраженияThe extraction pole is prepared by carrying a transport drift and a ventilation drift along the strike of the formation. 10 After preparing the pole, it is started up by working with a long clearing face. The line of the latter is located perpendicular to the drifts. Coal is excavated by applying vertical slotted cuts in the bottomhole normal to the reservoir at the same time along the entire length of the lava with a depth equal to 1/2 of the reservoir thickness, located at a distance L from one another, determined from the expression

ь = ол1/l = ol 1 /

’ Еп»’Еп»

Используя энергию опорного давления в виде отжима уголь разрушают с последующей транспортировкой его к транспортному штреку.Using the energy of the reference pressure in the form of extraction, coal is destroyed with its subsequent transportation to the transport drift.
