一、矿井概况 淮北矿务局朔里煤矿1981年核定生产能力为115万t,1983年实际出煤145万t。其井田内含石炭二迭系煤4层,煤层倾角20°～30°,平均厚度2.3m。属高沼气矿井。正常涌水量为360m~3/h。 矿井采用立井单水平分区式开拓,多风井混合式通风,电机车、皮带机联合运输,一级排水。矿井采用传统的炮采和先进的综采,采煤方法为单一走向长壁和倾斜分层走向长壁。 二、生产掘进率逐步回归模型的建立
First, the mine profile Huaibei Mining Bureau Shuoli coal mine in 1981 approved the production capacity of 1.15 million t, in 1983 the actual coal 1.45 million t. Its mine field contains 4 layers of Carboniferous and Permian coal, the coal seam dip angle is 20 ° ~ 30 ° with an average thickness of 2.3m. Is a high biogas mine. Normal water inflow is 360m ~ 3 / h. Mine shaft with a single horizontal division of development, multi-shaft mixed ventilation, electric locomotive, belt conveyor, a drainage. The mine adopts the traditional artillery mining and advanced fully mechanized mining. The coal mining method is single wall to long wall and inclined to the long wall. Second, the gradual regression model of production drilling rate established
