摘要
采用突水系数法对象山煤矿北一采区11^#煤层突水危险性进行了预测,结果显示,北一采区西北角、东南角属于相对安全区,突水系数〈0.06 MPa/m,北一采区北部B6孔附近为相对危险区,突水系数在0.1-0.119 MPa/m之间,其它区域处在临界区。该研究成果可为矿井防治水提供参考依据。
Using water inrush coefficient method,the water inrush danger of 11^#seam was predicted in Beiyi mining area of Xiangshan coal mine. The results show that the northwest and southeast of Beiyi mining area is relatively safe and the water inrush coefficient is less than 0. 06 MPa / m,the north near B6 hole of Beiyi mining area is relatively risk and the water inrush coefficient is 0. 1 - 0. 119 MPa / m,and the other areas are critical region. The research can provides basis for mine water hazard control.
