摘 要:为研究华阳二矿81215工作面区域地表移动变形演化规律,采取综合观测措施对开采区地表情况进行考察,考察期60 d。通过对观测数据进行统计分析和反演成图可知,采面走向位置观测线下沉曲线呈勺子形,倾向位置观测线下沉曲线呈漏斗形,最大沉降值4 032 mm,下沉量和开采情况基本一致。To study the evolution law of surface movement and deformation in the 81215 working face area of Huayang No.2 Coal Mine,comprehensive observation measures were taken to investigate the surface conditions of the mining area for a period of 60 d.Through statistical analysis and inversion of observation data into graphs,it can be seen that the subsidence curve of the observation line at the strike position of the mining face was spoon shaped,and the subsidence curve of the observation line at the dip position was funnel shaped,with a maximum subsidence value of 4032 mm.The subsidence amount was basically consistent with the mining situation.
