彬长矿区巨厚顶板水减水思路与技术对策

Water reduction ideas and technical strategies of huge thick coal seam roof in Binchang Mining Area

彬长矿区是我国侏罗系煤田的典型代表,受顶板巨厚砂岩水害影响,矿井涌水量居高不下,威胁煤矿安全开采的同时造成大量水资源浪费。在总结相关工程经验的基础上,从减水技术体系构建的角度出发,以水文地质条件精细探查和含水层分层研究、导水通道探测、采动裂隙发育规律研究为基础,提出了减水技术对策。研究可为彬长矿区相关煤矿顶板减水提供参考,为国内其他煤田顶板水减水试验提供借鉴。

Binchang Mining Area is a typical representative of Jurassic coal field in China.Under the influence of water damage by huge thick coal seam roof,the mine water inflow is high,which threatens the safety of coal mine and causes a great waste of water resources.On the basis of summarizing the relevant engineering experience,from the perspective of constructing water reduction technology system,based on the fine exploration of hydrogeological conditions,the study of aquifer stratification,the detection of water conducting and the development law of mining-induced fracture,the paper puts forward the water reduction technical strategies of coal seam roof,which can provide reference for the roof water reduction of related coal mines in Binchang mining area and other domestic coal fields.
