摘要
为解决深部突出危险工作面安全高效开采技术难题,以丁6-32030采面为突破点,进行了设计优化,增加了采面储量,避免了频繁搬家倒面。实行了分源抽采瓦斯,有效降低了工作面的瓦斯压力、瓦斯含量,减弱了工作面瓦斯涌出量。实行了低机身采煤机改造技术,解决了煤机高度过大需破岩石带来的效率、效益问题。
To solve the problem of deep prominent dangerous working face safe and efficient mining technology,with Ding-6-32030 mining face as the breakthrough point,has carried on the design optimization and increased the mining reserves,avoid frequent moving surface.Source extraction gas,has effectively reduced the working face gas pressure,gas content,reduced working face gas emission.Implement the lower fuselage coal winning machine transformation technology,has solved the coal height is too large to be efficiency and effectiveness of the problems of broken rock.
