摘要
为切实搞好综采工作面的瓦斯治理工作,根据保护层开采理论,对新集一矿131303工作面下保护层开采技术进行现场考察,考察结果表明,下保护层11-2煤层的开采对被保护层13-1煤层突出危险性消除效果明显。试验结果对类似开采条件的矿井防治煤与瓦斯突出及瓦斯综合治理具有一定指导意义。
To effectively carry out gas workface governance,according to the protective layer mining theory,set a new protective layer under the Mine 131303 face mining technology on-site visits,study results show that under the protective layer 11-2 on coal mining were protective layer 13-1 to eliminate the effect of coal outburst obvious.The results of similar mining conditions of the mine coal and gas outburst prevention and comprehensive management of gas has a certain significance.
