【摘要】 22204综采面为矿井首个沿空掘进形成的采面,通过对采空区积水规律的分析和研究,提出松软厚煤层的矿井在积水采空区下沿空掘进期间防治水技术与方法,同时在采面形成前,在22204底抽巷做瞬变电磁勘探,对采面底板水害进行探查以及采面形成后,对采面水样进行化验、对比等综合水害防治手段的运用,确保了采面的安全回采。更多还原

【Abstract】 22204 fully mechanized mining face is the first gob-side driving face in a mine. Through the analysis and study of the law of water accumulation in the goaf, puts forward the technology and method of water prevention and control during the gob-side driving under the goaf with water accumulation in soft and thick coal seam. At the same time, before the formation of the mining face,the transient electromagnetic exploration is carried out at the bottom of 22204 roadway to advance the water hazard of the floor of the mining face. After exploration and formation of mining face,comprehensive water hazard prevention and control measures such as testing and comparison of mining face water samples are used to ensure the safe mining of mining face.更多还原
