远距离被保护煤层消突技术的研究

Study on Outburst Prevention Techniques for Remote Protected Coal Seams

为了防止突出煤层在采掘时发生煤与瓦斯突出,合理选择了保护层开采,并结合抽放远距离被保护层瓦斯的方法,有效地消除了被保护层的突出危险性,实现了煤矿安全生产及正常接替。

For the prevention of the occurrence of coal and gas outburst in outburst seam during winning and opening, using the method of reasonably selecting and extracting protective seam and practising gas drainage from remote protected seam effectively removed outburst hazard of the protected seam and realized safe production and normal alternation of a coal mine.
