摘要
在煤矿开采中,高瓦斯矿井存在着较大的开采危险性,结合实际落实的瓦斯治理技术而言,还存在一些问题。以某煤矿企业的2606高瓦斯U型通风工作面为例,上隅角和回风流的瓦斯浓度较高,且瓦斯治理的难度较大,如何了解并应用好瓦斯治理技术,便成为很多煤矿企业需要考虑的问题。为此,先阐述U型高瓦斯工作面的情况,然后分析预抽问题的影响因素,最后研究钻孔护孔、封孔联孔和抽采等方面的瓦斯治理技术,以期望可以降低U型工作面的瓦斯浓度,提高开采安全性。
In coal mining,high gas mines have significant mining risks,and there are still some problems when combined with the actual implementation of gas control technology.Taking the 2606 high gas U-shaped ventilation working face of a certain coal mining enterprise as an example,the gas concentration in the upper corner and return air flow is high,and the difficulty of gas control is relatively high.How to understand and apply gas control technology well has become a problem that many coal mining enterprises need to consider.For this purpose,this paper will first elaborate on the situation of the U-shaped high gas working face,then analyze the influencing factors of the pre extraction problem,and finally study gas control technologies in drilling protection,sealing and connecting holes,and extraction,in order to reduce the gas concentration of the U-shaped working face and improve mining safety.
