摘要:

为了掌握煤炭开采后对地表的影响,本文以晋煤集团成庄矿5310大采高工作面为例,建立地表移动观测站,收集地表岩层移动数据,并对观测数据进行分析,得到地表下沉曲线、地表沉陷影响范围和地表移动关键参数[1]。结果表明:大采高工作面开采后,地表移动和变形值较大,地表沉陷影响范围广,在走向上最大影响范围超过300m。

关键词: 大采高, 观测站, 地表移动, 地表沉陷

Abstract:

To grasp the influence on the surface after coal mined out. In this paper, using 5310 large cutting height workface in Chengzhuang Coal Mine of the Jincheng Coal Group as an example, surface move observation stations were built and then the surface strata movement data was collected and analyzed. The surface subsidence curve, surface subsidence influence scope and key parameters of surface movement were obtained. Results show that, after large cutting height workface mined out, surface movement and deformation value is greater, surface subsidence influence scope is wider and influence scope at the striking bearing is more than 300m.

Key words: large mining height, surveying station, surface ground displacement, surface subsidence
