Abstract
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.
