摘要
以王家岭煤业18104工作面为例,针对高瓦斯矿井工作面瓦斯治理开展技术应用研究,根据瓦斯涌出量预测计算分析了18104工作面瓦斯抽采的必要性和可行性,提出了18104工作面瓦斯抽采方案主要以本煤层瓦斯预抽为主,回采过程中采用高位定向钻孔抽采采空区瓦斯,工作面瓦斯治理效果达标,开采过程中未出现瓦斯超限现象。
Taking the 18104 working face of Wangjialing Coal Industry as an example,the technical application research on gas control in the working face of high gas mine is carried out.According to the prediction and calculation of gas emission,the necessity and feasibility of gas drainage in 18104 working face are analyzed.It is proposed that the gas drainage scheme of 18104 working face is mainly based on the gas pre drainage of this coal seam,and the high-level directional drilling is used to extract the gas in the goaf in the mining process,The gas control effect of the working face meets the standard,and there is no gas overrun in the mining process.
