| 摘 要： | 金川二矿区1178m分段巷道位于矿体上盘,采用直墙半圆拱断面,巷道建成后变形严重,经过多次返修,仍未解决其稳定性问题。为了查明巷道破坏状况,对变形严重地段进行了监测,得到巷道变形规律,并进行了原岩应力实测工作,查明了工程的地应力环境,在此基础上结合工程地质条件对巷道变形破坏原因进行了初步探讨。

| Abstract: | 1 178 sublevel drift of No.2 mining area of Jinchuan nickel mine locates in mine handing wall.The shape of course section is straight wall and half closed arch.The distortion and breakage of course is very severiously.The course was repaired times without number.For finding out the tunnel breakage condition,carried on a monitor towards transforming serious district,get tunnel to transform regulation,carrying on an original rock also should dint measure a work actually,finding out the ground of the engineering should the dint environment,at above work foundation,combine the engineering geology condition to transform breakage reason to carry on first step a study to the tunnel. |
