摘要
由整体顶梁组合液压支架组成的支护系统应用于长沟峪煤矿大倾角煤层开采中。经过近9个月的生产实践表明,整体顶梁组合液压支架基本上能够适应长沟峪煤矿大倾角煤层开采需要。针对生产实践中发现的矸石冲击支柱的问题,发明了门插式档矸板。
The support system that consists of the hydraulic supports with the integrated roof timber is applied in steeply dipping seam mining in Changgouyu Coal Ming in.Pass by nearly nine months＇ production practice showed that the hydraulic supports with integrated roof timber can basically adapt the mining requirements of Changgouyu steeply dipping seam.the hindering gangue plate like door bolt is invented for the problems of the gangue impact support in the production practice.
