【摘要】 地应力是引起各类工程地质灾害的根本作用力。本文基于安居煤矿的地应力现场实测，提出了巷道设计与维护建议。主要结论如下：(1)矿井最大主应力平均为50.57 MPa，方向为118.47°（E28.47°S）；(2)矿井属于水平应力占绝对主导的σ_H>σ_v>σ_h型应力场，在量级上属超高应力区；(3)矿井垂直主应力平均误差不超过6%，侧压系数λ处于1.15～1.41，平均为1.28；(4)巷道支护要以加强顶底板的初次支护强度为主。研究成果对矿井安全、高效生产具有借鉴意义。更多还原

【Abstract】 situ stress is the fundamental force that causes various engineering geological disasters. Based on the in-situ measurement of Anju Mine, some suggestions on roadway design and maintenance were put forward. The main conclusions were as follows:(1)the average maximum principal stress of the mine was 50.57 MPa, and the direction is 118.47°(E28.47° S);(2) The mine was absolutely dominated by horizontal stress σ_H>σ_v>σ_h type stress field, and belonged to the super-high stress region in the magnitude;(3)The average error of the vertical principal stress of the mine was not more than 6%, and the lateral pressure coefficient λ 1.15～1.41 with an average of 1.28;(4)The primary support strength of roof and floor should be strengthened for roadway support. The research results of this paper were of great significance to the safe and efficient production of coal mines.更多还原
