深部煤炭资源采选充绿色化开采理论与技术

Theory and technique of greening mining integrating mining,separating and backfilling in deep coal resources

深部煤炭资源开采已势在必行,但面临更加复杂的开采环境、更加危险的开采扰动诱导潜在灾变过程。结合深部煤炭开采"四高一扰动"的挑战与充填开采在岩层控制等方面的技术优势,总结分析了深部充填开采面临的五大技术难题,提出深部煤炭资源采选充绿色化开采构想,即直接在井下构建煤炭开采、煤矸分选与矸石就地充填一体化生产系统,形成深部煤炭采选抽充防协同生产模式,实现深部煤炭及伴生资源的安全高效及绿色开采。该构想的初步技术体系已基本形成,并在平煤集团十二矿、开滦集团唐山矿等深部矿井建立了示范工程或基地。后续将继续深入开展深部充填开采岩层控制等6个基础理论方面的研究工作,创新采选充绿色化系统布置、自动化充填、物料大流量输送、煤矸智能分选等7项关键技术,形成深部煤炭资源采选充绿色化开采的系列理论与技术体系,为实现深部资源绿色化开采提供可靠基础。

Deep resource exploitation is imperative,but it is facing with more complicated mining environment and dangerous mining disturbances to induce the potential catastrophe process. Combined with the challenge of ＂four high and one disturbance＂in deep coal mining and the technical advantages of backfilling mining in ground control,this paper summarizes five major technical problems faced by deep backfilling mining,thus the conception of green mining integrating mining,separating and backfilling in deep coal resources is put forward. The theoretical research and technical system of the conception have been basically formed which has been carried out in typical mines such as the 12 th Coal Mine of Pingdingshan Group and Tangshan Coal Mine of Kailuan Group. In order to build integral theories and technology system of the green mining integrating mining,separating and backfilling in deep coal resource,backfilling and ground control theory in deep coal mine and five other basic theories need further researches and beyond that,sev-en key technologies such as the layout of mining-dressing-backfilling green mining system,automatic backfilling,mass flow material transportation and intelligent coal-waste separation need to be developed. These theories and techniques provide a reliable basis for realizing the safe,efficient and green mining of deep resources.
