综采工作面初采顶板分析与来压控制

Analysis of Roof and Pressure Control in the Initial Extraction at the Fully Mechanized Working Face

综采工作面顶板初次来压时顶板压力及顶板下落后潜在位能释放对工作面破坏性极强,通过对顶板来压跨距及潜在位能释放等问题的计算与分析,找出解决缓解和减小顶板来压当量的措施和办法,可减小综采工作面初次来压对工作面的破坏,为企业安全生产做好指导工作。

The potential energy release exerted a destructive influence on the fully mechanized working face after roof pressure and falling when the first roof weighting occurred. By calculating and analyzing the roof weighting span and the potential energy release, we aimed at finding measures to mitigate and reduce roof pressure equivalent, mitigate the damaging effect of the first roof weighting on the working face and better guide safety in production for enterprises.
