缓倾斜中厚多层矿床卸压开采技术方案探讨

Discussion on technical proposal of pressure-relief mining for gently-inclined medium thick multilayer deposits

在分析国内外卸压开采技术研究和应用现状的基础上,探讨了缓倾斜中厚多层矿床卸压开采的必要性和可行性;分析了典型缓倾斜中厚多层矿床开采特征,提出了结合支护的卸压孔-卸压巷组合卸压开采技术方案;结合钻孔卸压等卸压开采技术的可行性;并就回采-卸压开采方案连续化、程序化设计等技术难点,提出了卸压开采方案选择、优化和工程布置相应的技术措施。

Based on the analysis of pressure-relief mining tech- nology research and application at home and abroad, discussion is conducted on the necessity and feasibility of gently-inclined medi- um thick multilayer deposits and the characteristics of mining of the typical gently inclined medium thick multilayer deposits are analyzed, coming up with the proposal for drill hole-roadway pressure-rellef combined mining technology with support. The corresponding technical measures for selection , optimization and engineering configuration of pressure-relief mining are proposed addressing the design of continuation programming and other technical difficulties of the stoping-pressure-relief mining propos- al.
