摘　　要：总结分析了煤矿深部开采面临的主要技术问题,并就解决这些关键技术问题提出如下措施:加强深部地质工作,了解深部复杂多变的煤岩体特征,对深部开采进行统筹规划,合理开拓开采部署,尽可能防止采动和煤柱应力叠加;改进围岩的控制技术,限制围岩变形破坏;开辟新的思路和研究可行的技术途径,变热害为地下热能源利用等的多资源研究开发利用思路.加大科技创新的力度,解决关键技术难题,采用先进的技术和装备,降低和防范深部开采带来的安全风险.The key technical problems in deep mining were summarized and analyzed and some countermeasures to solve them were also presented. Firstly, the mining induced movement and superposed stress of coal pillars should be avoided as much as possible by strengthening the geological survey in depth to make clear the features of coal seams and rocks. On the basis of this, the overall plans can be made for the deep mining. Secondly, the controlling technique over the surrounding rocks should be improved to limit the amount of the distortion. Thirdly, some new ideas and ways should be considered, for example, changing the heat disaster to geothermal energy for using. In a word, the scientific and technological innovation should be strengthened and the advanced technique and equipment adopted in order to reduce and prevent the danger resulted from deep mining.
