随着开采的延伸和开采强度的加大,该矿采煤队工作面上隅角、软、硬帮端头近期仍然发生瓦斯超限现象,迫使场子无法组织正常生产。要解决瓦斯超限问题,切实做好瓦斯治理工作,瓦斯抽采是关键,然而做好瓦斯抽采工作就必须要在井下特定的环境中克服重重困难才能达到抽采的目的。只有找到影响瓦斯抽采效果的因素,并提出相应对策才能有效治理瓦斯。审视采煤队面临的窘境,我们不难发现造成瓦斯抽采效果不理想的原因是多方面的、深层次的。既有地质环境、自然方面的因素,又有过高位钻场和抽采工艺不成熟造成的问题。
With the extension of mining and the increase of mining intensity, the gas overrun phenomenon still occurs in the upper corners of soft coal and hard ends of coal mines in the coal mines for a long time, forcing the sites unable to organize normal production. To solve the problem of gas overrun, to do a good job gas control work, gas drainage is the key, but to do gas drainage work must be in a specific underground environment to overcome the numerous difficulties in order to achieve the purpose of extraction. Only to find the factors that affect the gas extraction effect and propose appropriate measures to effectively control gas. Looking at the dilemma faced by the coal mining team, we can easily find that the causes of unsatisfactory gas drainage are manifold and deep-seated. Both the geological environment, natural factors, there are too high drilling and pumping technology caused by immature problems.
