复杂条件下综采工作面回撤通道支护研究

Remove channel back to the fully mechanized mining face under complicated conditions supporting design and Application

综采面在回采过程中经常遇特殊地质构造,造成顶板破碎、局部冒顶现象,特别是在回采面形成回撤通道期间,地质构造严重影响回撤通道支护质量。本文以大同煤矿集团永定庄煤业公司8112工作面为例简单浅析了过特殊地质构造时回撤通道顶板及煤壁支护设计,力求保证提高回撤通道支护效果。

It often met the special geological structure in mining process of fully mechanized coal mining face, which resulted the broken roof, local caving phenomenon, especially during the formation of recovery room, the geological structure seriously affect the recovery room supporting quality. Taking the 8112 working face of Yongding coal mining company of Datong Coal Mine Group as an example, this paper simply analyzes the support design of the roof and the coal wall of the retreating channel during the special geological structure, and tries to ensure the support effect of the retreating passageway.
