摘要
以官地煤矿与天龙山森林公园重叠区采煤工作面地表塌陷区为研究对象,采用现场勘探和统计法对地裂缝发育情况进行统计,用Arc GIS软件将地裂缝展布与采掘工程平面图、地形图叠加,分析地裂缝存在对地表植被覆盖影响。研究表明:煤炭开采后地裂缝主要发育在采面切眼、停采线、护巷煤柱两侧及巷道交汇处,在地表起伏明显区域地裂缝数量明显增加;距地裂缝2 m以内的植被覆盖与地裂缝关联度大,2 m以外则关联度不明显;地裂缝对其附近4 m范围内的植被生长影响明显。
Taking the surface collapse area of the coal face in the overlap area of Guandi Coal Mine and Tianlongshan Forest Park as the research object, the field exploration and statistical method were used to make statistics on the development of the ground fissures. The ground fissure distribution was superposed with the mining engineering plan and the ground shape map with Arc GIS software to analyze the impact of the ground fissures on the surface vegetation coverage. The results showed that after coal mining, the ground fissures are mainly developed in the cutting hole, stopping line, both sides of the coal pillar and the intersection of the roadway, and the number of ground fissures increases obviously in the area with obvious surface relief;the vegetation coverage within 2 m from the ground fissures has a large correlation with the ground fissures, and the correlation is not obvious beyond 2 m;the ground fissures have a significant impact on the vegetation growth within 4 m around the ground fissures.
