摘要
矿区因煤炭资源开采造成地面变形,从而引发的地质灾害现象一直不同程度存在。如何防治开采沉陷引起的环境破坏和地质灾害,已经成为矿区各个煤矿刻不容缓的任务。以下峪口煤矿23208工作面地表移动测量为例,探讨煤矿开采区工作面地表移动观测站的建立与测量方法,并通过数据采集、处理和分析,获得该工作面地质采矿条件下准确可靠的地表移动变形参数,分析了地表移动变形规律。该方法可为煤矿其他工作面的开采,提供经验数据,为矿区地质灾害防治提供前瞻性对策和指导,降低矿山开采的生态和环境成本。
The ground deformation caused by mining of coal resources in mining areas has always caused geological disasters to varying degrees.How to prevent environmental damage and geological disasters caused by mining subsidence has become an urgent task for all coal mines in mining areas.Taking the surface movement measurement of the No.23208 working face in Xiayukou Coal Mine as an example,the surface movement observation station and observation method were designed.Through collecting,processing and analyzing the observation data,the parameters of surface movement and deformation under the geological mining conditions of the working face were obtained,and the law of surface movement and deformation was analyzed.The research can provide empirical data for the other working faces in coal mines,and give forward-looking countermeasures and guidance for the prevention and control of geological disasters in mining areas,so as to reduce the ecological and environmental costs of mining.
