摘要:
为了揭示高强度开采低瓦斯煤层而导致的高瓦斯矿井的瓦斯涌出和瓦斯防治特点，以王家岭矿为例，采用现场跟踪考察和测试的方法，分析了回采工作面瓦斯涌出特征，提出了适用该矿的瓦斯治理措施，并对瓦斯治理效果进行了评价。针对该矿低瓦斯煤层高强度开采的特点，提出了“以顶板高位定向钻孔和上隅角埋管抽采卸压瓦斯相结合”的瓦斯治理模式，瓦斯治理效果的现场考察发现：顶板高位定向钻孔平均抽采纯量为1.33 m3/min，最大为2.82 m3/min，上隅角平均瓦斯抽采纯量为0.91 m3/min，最大为1.30 m3/min。
Abstract:
In order to reveal the characteristics of gas emission and gas control in high gassy mine caused by high intensity mining of low gassy coal seam,this paper takes …… Taking Wangjialing coal mine as an example,the characteristics of gas emission in the mining face were analyzed by using the methods of field tracing investigation and testing. The gas control measures applicable to this mine were put forward,and the effect of gas control was evaluated. Aiming at the characteristics of high intensity mining in the low gassy coal seam of this mine,a gas control mode of combined drainage of pressure relief gas by the roof high level directional drilling and the embedded tube in the upper corner was put forward. The field investigation of gas control effect showed that the average pure gas drainage rate of the roof high level directional drilling was 1.33 m3/min,with the maximum value of 2.82 m3/min,and the average pure gas drainage rate of the upper corner was 0.91 m3/min,with the maximum value of 1.30 m3/min.
