巷道底鼓整修中的锚注支护应用

Application of Anchor Supporting in the Renovation of the Floor Heave of the Roadways

巷道底鼓现象作为深部开采中的多发事故,对于井下生产运输的安全和连续有着严重威胁。结合具体工程实际,运用数值模拟技术,对底鼓优化治理方案的可行性进行对比分析,并通过实际检验表明,底板锚注+两帮补强的方案能实现底鼓问题的有效治理,希望能为其它相似问题的处理提供借鉴与参考。

Roadway floor heave is a kind of accidents that frequently occur in deep extraction which poses a serious threat to the safety and continuity of underground production and transportation. Combined with specific engineering practice, this paper carr- ied out comparative analysis on the feasibility of the optimized control methods of the floor heave by using numerical simulation technology. The practical test results showed that the scheme of backplane anchor plus strengthening achievement with both assis- tances could effectively solve the floor heave problem, hoping to offer reference for dealing with other similar problems.
