摘要
关闭矿井的关键环节是封闭井筒,井筒封闭的关键环节是充填段下部受力密闭墙的设置,本文以山西华润煤业有限公司大雁煤矿井筒封闭为工程背景,通过方案分析比较与密闭墙受力计算,合理确定了工程技术方案,确保了矿井关闭工作的顺利进行、杜绝了相关安全隐患。
The key link of shutting down the mine is the closed wellbore, and the key link of wellbore closure is the setting of the lower force closed wall in the filling section, this paper takes Shanxi Huarun Coal Industry Co., Ltd. the wellbore closure of Wild Goose coal mine as the engineering background, through the scheme analysis comparison and the force calculation of closed wall, reasonably determines the engi neering technical scheme, To ensure the smooth operation of the mine shutdown work, to eliminate the related safety risks.
