鄂托克旗特殊地质条件下采空区治理

Goaf governance under Etuokeqi special geological conditions

由于鄂托克旗地层中第四系厚度薄致使没有足够量的黄土可利用,对当地采空区防灭火困扰极大,提出使用爆破的方法治理上覆岩层塌陷采空区,结合采空区位置提出中深孔崩落法、切割深孔崩落法、反铲放塌剥离物回填的治理措施。

Since the quaternary thickness is thin in Etuokeqi stratum, loess is insufficient to be used, which brings great troubles for local goaf fire prevention and extinguishing. The article presents the governance means of using blasting method to collapse the goaf of overlying strata. Combining goal position, the author presents some governance measures, such as deep hole caving method, cutting deep hole caving, backhoe put collapse stripping backfill.
