摘要:
本文针对布尔台煤矿42103首采综放面初采期间矿压异常显现特征,分析了矿压显现异常的原因,总结了控制综放面矿压异常显现的综合措施,包括降低顶煤放出速度、采用初撑力控制阀、提高支架额定工作阻力及保证支架合理的工作位态等,取得了良好的效果。

Abstract:
Based on the characteristics of abnormal strata behaviours of 42103 first fully mechanized caving face during the initial mining period in Bu'ertai Coal Mine, this paper analyses the causes of abnormal pressure and sums up some comprehensive measures of controlling pressure anomalies, including lowering the top coal release speed, using the pump regulator, improving rated working resistance of stents and ensuring reasonable working-bit mode, etc., which have achieved good results.
Key words: Fully Mechanized Caving Face, Mine Strata Pressure, Abnormal Strata Behaviors, Control Measures
