Water filling sources of underground mine in Pingshuo mining area have Quaternary pore water,surface water,Permo-Carboniferous sandstone fissure water and Ordovician limestone karstic fissure water.

During the Pingshuo Coal Company Antaibu No.

In this paper,the partial parameter of the hoisting system,drainage system,ventilation system,feed system of the check standard of the coal mine production are optimized and qualified according to the open problem of the production check in the subterranean coal mine at the present tine.

The numerical simulation study on the reasonable distance between the open pit slope and mine;

The three series of completion techniques(conventional perforation,TCP and new completion) are formed including fourteen technologies,which are adaptable to different geologic settings and hole conditions.
