摘要： The present invention discloses a mine exploitation, separation, filling and treatment exploitation method, including main sources of gangue on a small-volume gangue exploitation working face and gangue reducing measures; system layout, equipment and separation technology for coal gangue separation; system layout, equipment and production technology for filling synergistic caving type coal efficient stoping; pretreatment and pre-control measures for environmental influence before and after gangue filling; and design principle and design steps of the mine “exploitation, separation, filling and treatment” exploitation method. The method not only solves the problem of long-distance transportation of gangue, reduces the lifting cost of underground gangue and relieves the pressure of mine auxiliary lifting and ground coal washing plants, but also may effectively treat coal mine gangue, reduce the surface stacking area of coal gangue, reduce the damage to the ecological environment of a mine and protect an ecological environment. Furthermore, a gangue filling and coal efficient stope face has high single production efficiency, may meet the requirements of modern mines for production capacity, and application prospects are wide.

摘要： A mine exploitation method based on stoping, separation and filling control is disclosed herein. The method includes deploying a gangue-less coal mining system; choosing a suitable coal and gangue separation method according to a separation requirement; choosing a suitable filling method according to mine geology, production conditions and rock stratum control requirement; reversely calculating a filling rate according to gangue discharge requirement and control indexes by utilizing theoretical calculation, simulation and experiment; determining a filling process and a separation process according to the filling rate; and feeding back and adjusting the filling process and separation process parameters by monitoring filling and control effect indexes.

摘要： The present invention discloses a mine exploitation, separation and filling and X exploitation mode, including four “exploitation, separation and filling and X” exploitation modes, namely an “exploitation, separation and filling and retaining” exploitation mode, an “exploitation, separation and filling and treatment” exploitation mode, an “exploitation, separation and filling and extraction” exploitation mode, and an “exploitation, separation and filling and control” exploitation mode. The selection of the “exploitation, separation and filling and X” exploitation mode is determined by actual engineering needs. A goaf filling rate is designed to meet the actual engineering needs of the mine, solve the technical problems in mine resource exploitation, and realize the objective of green, harmonious and safe exploitation of coal resources. Compared with an original “exploitation, separation and filling” exploitation mode, the “exploitation, separation and filling and X” exploitation mode is more systematic and comprehensive and is beneficial to engineering promotion and application.
