Aiming at controlling the land subsidence,the optimal exploitation scheme for each aquifer is presented,which provides a scientific foundation for exploiting groundwater reasona.

Numerical modeling research of mining schemes determination at Shizhuyuan polymetallic ore deposit;

To fully exploit the coal resource under village, and to ease the conflict of exploitation and mining, so as to prolong service time of the mine and reduce the damage to the buildings caused by mining activity under village to its minimum, the mining scheme is studied.

By applying the analytic hierarchy process,mining schemes of No.

Because the optimizing selection among the finite mining methods has great economic and social effects, decision making under decision group is necessary to be carried out.

According to the geological and mining conditions of a certain mining area, learn the feasibility of mining method, predict the final and dynamic result, put forward the conclusion that strip mining is the feasibl.
