摘要

In order to guide the safety production in Huangling No.1 coal mine, based on the analysis of the coal seam occurrence characteristics on 304 coal mining face, a 3D geological model of the coal mining face was established. This was done by using the rock and loess mechanics experiment results of the roof above the No.2 coal seam as the parameters. Then, through the FLAC3D software, a numerical simulation was made on the roof rock destruction caused by the coal mining. The paper analyzed the seam overburden stress distribution and seam roof damage and deformation characteristics. Compared with empirical formula calculation results and drilling measurement data, it was concluded that the height of caving zone and fissure zone was 69m.
