近距煤层开采井巷压力显现特征及控制

Discussion on the Apperance Characteristics and Control of Roadway in the Coures of the Mining for Distance Seame

通过对近距离煤层开采过程中 ,井巷压力显现的观察与分析 ,提出井巷在不同压力影响阶段 ,井巷变形破坏的不同表现。以便采取不同的支护手段 ,同时指出回采工作面巷道布置设计、支护选择等影响近距离煤层井巷维护的重要因素 ,以求主观支护措施同客观压力显现规律相适应 ,保证井巷的使用安全。

By observing and analysing the pressure appearance in the course of the mining for near distance seame,puts forward that mining face roadway design and support selection are influenced near distance seame roadway maintenance,the different support measures should be adopted to meet the needs of mining pressure appearance rule,ensure the safety of roadway.
