煤炭科学开采与开采科学

从安全生产、机械化或自动化开采、共伴生资源共同开采、保护环境、降低开采直接成本、资源利用最大化、科学规划等方面详细阐述了煤炭科学开采的基本要求。介绍了国内外在煤炭科学开采方面的研究现状与进展,对比分析了国内外科学开采的共同点与差异。提出了我国实现煤炭科学开采需要从技术进步、思想观念、法律法规、基础研究与人才培养等方面入手。提出了煤炭开采今后需要在采矿开挖卸荷与偏应力作用、采动应力场动态变化、深部煤岩体的力学行为、煤岩柱的长期强度、采场的系统刚度等10个方面加强研究。

Sustainable coal mining and mining sciences

The basic requirements of sustainable coal mining were described in detail from various aspects-safe mining,automatic mining,co-mining of coal and accompany resources,environment protection,direct cost reduction of mining,maximization of resource utilizing and sustainable planning.Overseas and domestic research status and progress of sustainable coal mining were introduced to make a comparative analysis for similarities and differences.Accordingly,the realization of domestic sustainable coal mining was proposed to focus on five aspects-technical development,ideological progress,optimization for laws and regulations,basic researches and talent cultivation.At last,coal mining was suggested to be continuously studied from all ten aspects-mining including unloading and deviatoric stress,dynamic change in mining stress field,mechanical behavior of deep coal-rock mass,long-term strength of coal-rock pillar,stiffness of stope system,etc.
