Изобретение относитс к горной про ьшшенности и предназначено дл подготовки шахтных полей.The invention relates to mountainousness and is intended to prepare mine fields.
Целью изобретени вл етс снижение затрат на подготовку путем сокращени объемов проведени подготовительных выработок.The aim of the invention is to reduce the cost of preparation by reducing the volume of development workings.
Способ осуществл етс следуюнщм образом.The method is carried out as follows.
На отраточном- горизонте провод т полевой штрек, а на .вентил даон- ном горизонте используют в качестве вентил ционного существующий откаточный полевой штрек. Шахтное поле раздел ют по простиранию откаточными и вентил ционными промржуточны- ми квершлагами на отдельные односторонние выемочные пол (блоки), смещаемые относительно блоков верхнего горизонта в направлении прин того пор дка отработки шахтного пол на величину, равную (0,5 - 1,0)ЬOn the horizontal horizon, a field drift is conducted, and on the ventilation daone horizon, the existing haulage field drift is used as a vent. The mine field is divided, along the strike, by haul and ventilation intermediate quarters into separate one-sided excavation fields (blocks) displaced relative to the blocks of the upper horizon in the direction of the adopted order of mining of the mine floor by an amount equal to (0.5 - 1.0) B

где Ь - ширина межблоковых предохранительных целиков, которые оставл ют между выемочными блоками на рею высоту этажа и располагают сту- 5 пенчато. Этажным аккумулирующимwhere b is the width of the interblock safety pillars, which are left between the excavation blocks to the height of the floor and have a stack of foam. Storey accumulating
штреками придают уклон не менее 0,05 в сторону аккумулирующих промежуточных квершлагов, проводимых с таким же уклоном. При этом ниже почвы этажных штреков создают свободные от разработки зоны, в контуре которых , провод т промежуточные вентил ционные квершлаги.drifts impose a slope of not less than 0.05 in the direction of accumulating intermediate crosscuts, conducted with the same slope. At the same time, below the soil of the floor drifts, create zones free from development, in the contour of which, intermediate ventilation cups are held.
Промежуточные вентил ционные квершлаги провод т горизонтальными из существующего откаточного полевого штрека верхнего этажа, В створе с вентил ционными квершлагами на откй- точном горизонте провод т откаточные 20 промежуточные квершлаги и придают им уклон не менее 0,05 в сторону полевого штрека.Intermediate ventilation openings are conducted horizontally from the existing upper ground floor drift road. In the alignment with the ventilation openings on the lateral horizon, the opener 20 intermediate quarters are conducted and give them a slope of not less than 0.05 to the side of the field roadway.
