坚硬顶板周期来压对瓦斯涌出的影响与对策

Wu 8 seam roof cycle hard to pressure on the impact of gas emission and response

运用回归分析的方法,通过对中平能化集团天安六矿戊8煤工作面回采时,周期来压步距的测定与瓦斯涌出规律性分析,从周期来压对瓦斯涌出影响的机理、煤层内瓦斯活动规律等方面验证了戊8煤坚硬顶板周期来压与瓦斯涌出显著相关的特性,并给出了应对的策略。

The use of regression analysis method, Wu 8 mining coal face of tian＇an No. 6 mine of Zhongping Energy and Chemicals Group, the cycle pressure from the determination of step with the regularity of gas emission analysis, pressure from the cycle of the mechanism of the effects of gas emission , coal seam gas activities in the areas of the law to verify the E 8 seam roof cycle hard to pressure and gas emission characteristics were significantly correlated, and are given strategies to deal with.
