The desert runoff area is an important water source in Yushen mining area. To protect water resource in des- ert,and ensure safe and efficient coal mining,the authors develop a key technology for coal mining with water con- tained in desert. The influence factors and the zoning standards of the coal mining with water contained are analyzed by means of field measurement and numerical calculation. The results show that:coal miming under river recharged by desert may lead to two type of water loss,i. e. ,flow in river and groundwater in recharge area. The recharge area is di- vided into water and sand inrush region,water inrush region,leakage region and water retention region. The residual thicknesses of aquifuge can be regarded as a safe indication whether the flow in river could pour into worked-out sec- tion or not. Repairing cracks in leakage area,building dam drainage in water bursting area,using the hydrodynamic conditions and controlling sand source flow technology can control in water and sand inrush area. The comprehensive treatment of mining area made a successful engineering application for the mining face across trench.
