| 摘 要： | 基于北皂煤矿海域扩采区为三软地层,为了合理布置巷道,解决巷道支护较困难问题,采用地应力解除法,使用空芯包体应力计对海域扩采区进行了地应力测量,通过对所测数据进行分析得到了北皂煤矿海域扩采区水平构造应力与垂向应力的比值平均为1.56,地应力场以水平构造应力为主,最大主应力方向为北偏东约45,°因此建议巷道轴线方向应尽可能沿北东方向布置。

| Abstract: | Based on the expanded mining area of Beizao Mine under sea was a three soft seam,in order to have a rational layout of the mine gateway and to solve the support difficulty problem of the mine gateway,the ground stress released and eliminated method was applied with the free space core pack stressmeter to have the stress measurement to the expanded mining area under the sea.The analysis on the measured data showed that the ratio between the horizontal structure stress and the vertical stress in the expanded ... |
