Abstract：In order to realize a safety and high efficient green mining of the deep coal,the paper analyzed the technical difficulties of the gas,limestone water,ground pressure and ground temperature aspects faced to the deep coal mining in Huaina Mining Area and the faced challenges and provided seven key technical countermeasures to the coal mining in the deep mine,including the optimized mining layout,integrated coal resources,innovated gas control mode and innovated gas control demo project.A mine full face hard rock roadway boring machine in a deep coal mine and a smaller mine pipe jacking machine and others were researched,developed and tested and thus "mechanization,automation,intelligent and information" were continuously promoted to a new level.The innovated "drilling,discharging and grouting" integrated limestone water prevention and control technology,innovated mine cooling technology,innovated stability control and support technology of the deep mine roadway would promote and coordinate the green mining complete technology in order to solve the key technical problems of the deep mining,to promote the coordinative green development of the deep mine and to improve the safety production and comprehensive effect of the deep mine.
