摘要
为高效抽采中梁山南矿急倾斜近距离上保护层开采后的卸压瓦斯,开展了急倾斜近距离上保护层开采卸压瓦斯运移规律研究,利用保护层开采产生的"卸压增透效应",结合该矿实际情况,对被保护层的卸压瓦斯抽采参数进行了优化。
An investigation of the optimization designing on extracting pressure-relief gas of up-protective layer mining in steep inclined close thin seam was carried out to extract effectively the pressure-relief gas of up-protective layer in Zhongliangshan south mine.The pressure-relief law of protected layer after mining up-protective layer was investigated by experimentally.Optimization design on pressure-relief gas extracting characters of up-protective layer were studied by utilizing the effect'pressure-relief to strengthen permeability' and integrating with mineral practical conditions.
