爆破封井技术应用于矿山地质灾害的防治

Application of Explosion Well Cementation Technology in Prevention and Control of Geologic Hazard

制盐企业矿山盐井由于材质腐蚀、地质变化等原因损坏,水溶开采卤水时,造成地面塌陷,出现地质灾害,坏井的封堵彻底处理很困难,经过反复试验,采用爆破法封井非常成功,从而对盐井损坏开采过程中造成地面塌陷出现地质灾害起到了很好的防治作用。

Due to such damages as material corrosion and geologic changes etc,during solution mining, brine well in salt making enterprises is prone to cause ground subsidence and geologic disaster.It is difficult to thoroughly block the waste well. Through repeated experience, explosion well cementation is very successful and it can well prevent and control the geologic hazard resulting from ground subside during brine well extraction.
