【摘要】：针对西部生态脆弱矿区富煤贫水特征和原生态保护要求,建立集开采和生态保护为一体的"现代开采生态系统";基于采前地下水及地表生态的稳定性关系或生态"原态"约束,提出煤水资源开发中的"煤-水仿生共采"理念、煤炭开采与水资源开发及地表生态保护同步的"煤-水仿生共采"模式;按照"隔离-导流-控制"的仿生共采新思路、提出"隔离层控制"原理和开采"地下水漏斗聚集"调控效应;构建了集分区设计、隔离重构、仿生控制为核心的煤-水仿生共采保护控制关键技术体系;开发了"压裂-开采-注浆"开采隔离保护工艺、地下水汇集调控关键技术。
[Abstract]:In view of the characteristics of rich coal and poor water and the requirements of original ecological protection in the ecologically fragile mining areas of western China, a "modern mining ecosystem" which integrates mining and ecological protection is established, based on the stability relationship of groundwater and surface ecology before mining or the constraints of ecological "origin".This paper puts forward the concept of "coal-water bionic co-mining" in the development of coal water resources, the mode of "coal-water bionic co-mining" which synchronizes coal mining with water resources development and surface ecological protection, and the new bionic co-mining idea of "isolation, diversion and control".The principle of "isolation layer control" and the regulation effect of mining "groundwater funnel accumulation" are put forward, and the key technology system of coal-water bionic protection control is constructed, which is based on the design of partition, isolation and reconstruction, and bionic control.The "fracturing-mining-grouting" mining isolation protection technology and the key technology of groundwater collection and control have been developed.
