摘要
我国深部煤炭资源丰富,煤炭开发已逐步向深部转移,深部灾害防控和矸石等矿山固废排放问题日趋严峻。充填开采是实现灾变调控、地表沉陷控制和矿山固废处置的重要手段,已在我国煤矿绿色开采、矿压控制与岩层移动等领域广泛应用。然而,相对浅部,深部“三高一扰动”条件下充填开采岩层控制更为复杂,因此,构建深部绿色充填开采岩层控制理论与方法体系,对于深部煤炭资源安全高效开采具有重要意义。本文在系统分析深部充填开采岩层控制面临挑战基础上,提出了深部充填开采关键科学问题、研究目标与总体思路,并从多场耦合作用下充填体-围岩交互作用机理、强扰动条件下充填采场矿压分析模型、深部充填开采岩层控制方法、充填体与地下水环境互相影响四个方面阐述了相关研究进展。
Deep coal mining in China developed rapidly in recent years because of abundant deep-lying coal resources in this country,and,at the same time,the problems of deep geological disaster and disposal of solid waste like gangue get worse.Solid backfilling mining is an efficient method for problems including disaster prevention&control,subsidence control and solid waste disposal,and thus widely used in engineering field like green mining,strata and mining pressure control.However,unlike shallow coal mining,overlying strata control in solid backfilling mining become more complex under the influence of geological environments with three“high”and one“disturbance”.Therefore,building theoretical and method system for overlying strata control in deep solid backfilling mining is of important to safety and efficient deep-lying coal resources mining.Based on systematic analyzing difficulties confronted by overlying strata control in deep solid backfilling mining,this paper proposes the key scientific problems,research purpose and overall approach of deep solid backfilling mining.Four important research progress,including interaction mechanism between backfilling body and surrounding rock under multi-field coupling,theoretical model of deep solid backfilling mining pressure under the environment of strong distribution,strata control method for deep solid backfilling mining and interaction effect between solid backfilling body and underground water,are also summarized.
