半煤岩综掘巷道分割分运技术研究

Research on individual cutting and transporting technology in semi coal and rock roadways

半煤岩巷道采用综掘机掘进,进尺明显增加,施工人员减少,安全生产效益得到提高,同时也提高掘进工程质量。但掘进工作面煤矸混运直接影响煤炭质量。利用综掘机掘进的灵活性,采取分割分运技术,能够有效地解决掘进工作面煤矸分离问题。

The use of roadheading makes the footage of semi coal and rock roadways increase significantly, reduce the construction personnel, improve the safety production efficiency, but also increase the excavating engineering quality. But the mixed transportation of coal and gangue directly affects the coal quality of excavatingface. By using the flexibility of roadheading, takes the coal and coal refuse separation technology, can effectively solve the problem of working face coal gangue separation problems.
