新集二矿1煤具有特低硫、特低磷、富焦油及中高发热量,煤质优良,经济效益显著、社会效益长远。为确保1煤工作面连续开采,需提前掘进相邻接替工作面的机巷,受工作面回采影响,矿压显现明显,掘进时需对机巷进行加强支护。以新集二矿210102机巷为例,在210106工作面采动压力影响下,根据巷道顶底板移近量及两帮位移量优化巷道支护设计,对采动压力影响下沿空掘巷支护设计及已掘巷道在采掘压力影响下修护具有一定的借鉴意义。
Xinji No. 2 Mine 1 coal has ultra-low sulfur, ultra-low phosphorus, rich tar and high heat, coal quality, significant economic benefits, long-term social benefits. In order to ensure the continuous mining of coal face 1, the adjacent roadways of adjacent working face need to be drilled in advance. Affected by the mining face, the mine pressure is obvious, and the roadway needs to be reinforced to support. Taking 210102 mechanized alley of Xinji No.2 mine as an example, under the influence of mining pressure of 210106 working face, the roadway support design is optimized according to the approach amount of roof and floor of the roadway and two groups of displacement, Conservation design and has been digging roadway under the influence of mining pressure to repair a certain reference.
