为了改善强矿压冲击工作面及巷道支护状况,以华亭煤矿特厚煤层综放开采实践为基础,采用理论分析、实验与现场实测相结合的方法对冲击矿压的灾害特征及冲击倾向性进行分析,研制了新型工作面及巷道支护系统。研究结果表明：冲击矿压灾害具有突发性、剧烈性及巨大的破坏性,华亭煤矿5号煤层具有强冲击倾向性,顶板为弱冲击倾向性,具有较强的冲击危险,采用新型工作面端头支架、巷道超前支架及＂O＂形防冲击支架能够很好地解决矿井支护问题。

In order to improve the supporting conditions in roadways and working faces with strong rock burst,the theoretical analysis method,laboratory tests and field measurement were adopted to analyze the impact tendentiousness and the disaster features of rock burst,taking the fully-mechanized sublevel caving mining in the very thick seam of Huating mine as an example.The new types of support systems for working faces and roadways were developed.The results of the study showed that the rock burst disasters were of such characteristics as sudden occurrence,intenseness and great destruction.The 5th coal seam has strong probability of rockburst and its roof has weak proba-bility of rock bursts in Huating mine,then,the mine has strong rock burst risk.The new end hydraulic supports,the fore supports of roadways and O-shaped hydraulic supports adopted could solve the problem of rock burst risks in mine.
