摘　　要：煤层开采引起的采动裂隙的演变对于煤炭开采安全以及相邻含(隔)水层地下水演化具有重要的研究意义。本文通过分析采动裂隙研究的进程,将其划分为采动裂隙初识、演化模型模拟和演化规律的定性分析三个阶段,并分别进行浅析。通过对研究资料的梳理和归纳,发现采动裂隙的演化会破坏含(隔)水层骨架结构并引起地下水流场的改变,形成地下漏斗危害开采的安全。研究表明采动裂隙演化规律的研究是未来煤炭开采中的水灾害防治、水资源合理开发和高效利用的关键环节,同时提出了未来潜在的研究方向。The evolution of mining fissures caused by coal mining is of great significance to the safety of coal mining and the evolution of groundwater in adjacent aquifer. Based on the analysis of the process of study on mining-induced fractures, this paper divides them into three stages, the first knowledge of mining-induced fractures, the simulation of evolution model and the qualitative analysis of evolution law, and analyze them separately.By combing and summarizing the research data, it is found that the evolution of mining fissures will destroy the skeleton structure of the water-containing(isolated) layer and cause changes in the groundwater flow field, forming an underground funnel that endangers the safety of mining.The results show that the study of evolution law of mining-induced fractures is the key link of water disaster prevention, rational development and efficient utilization of water resources in coal mining in the future, and potential future research directions are also proposed.
