浅埋深厚煤层开采地表岩移观测分析

Observation and Analysis of Surface Rock Movement in Mining of Shallow Depth Coal Seam

为了分析色连矿浅埋深厚煤层开采区域地表岩移规律,在8101工作面地表设置测站,根据观测结果,计算给出了色连矿浅埋深厚煤层开采区域地表移动变形的相关参数,以及地表下沉速度和移动延续期等。结果表明:色连矿首采面地表活跃期短,但地表活跃期的下沉速度快、下沉量大、移动剧烈,达到总下沉量的95%。

In order to analyze the law of surface rock movement in mining area of shallow depth seam in Selian Colliery, a survey station has been set up on the surface of 8101 working face. According to the observation results, related parameters of surface movement deformation in shallow depth seam mining area, as well as the subsidence speed and movement duration are calculated and given in the paper. Results show that due to its shallow burial depth and thin bedrock, the active period of surface movement is relatively short, but the surface subsidence speed is relatively high and the surface movement is relatively violent. The surface subsidence in the active period of surface movement accounts for a large proportion of the total subsidence, reaching more than 95%.
