矿井充水因素分析及带压开采安全性评价

Analysis of mine water filling factor and safety evaluation of mining above confined water

本文以祥升煤业实际条件为工程背景,对井田内15下煤层的充水水源、突水通道等进行分析研究,并利用突水系数法对工作面底板突水危险性进行合理评价,计算结果表明15下煤层采区内突水系数均小于0.1MPa/m,属于带压开采安全区,制定完善措施后,可以进行安全开采。

Take the actual condition of Xiangsheng coal mine as engineering background, analysis the mining field on 15 下 coal seam source of water filling, water inrush channel, and use the water inrush coefficient method to reasonable working face floor water inrush risk evaluation,the calculation results show that within 15 下 coal seam mining under water inrush coefficient is less than 0.1 MPa/m, belongs to the safety of under pressure mining, formulate measures, can undertake safety mining.
