江西某采煤区地面塌陷地质灾害的分析

Geological Hazard Analysis of Ground Subsidence in Mining Area

分析了区内可采煤层的分布情况,收集钻孔资料中的煤层厚度、倾角、埋藏深度等,根据《建筑物、水体、铁路及主要井巷煤柱留设与压煤开采规程》中相关参数及经验数据计算出各钻孔的变形等级数值,并采用内插法得出该区煤层开采影响等级变形图。结合区内存在可溶性岩层,综合分析该区的地面塌陷地质灾害。

Based on the distribution of the main workable coal seam and the data of coal seam thickness,dip angle and burial depth,the paper makes a comprehensive analysis of the ground collapse geological hazards by calculating the deformation rate of every hole according to the relevant parameters and empirical data in"Regulations for Setting of Building,Water Body,Railway and Main Roadway Coal Pillar and Ground Coal Mining"and drawing the impact level deformation map through the interpolation calculation method.
