煤炭深部开采工艺变化对沉陷规律影响的实测分析
Measured analysis of the effect of changes in deep coal mining technology on subsidence laws
摘要
Abstract
To investigate the differences between surface subsidence laws in longwall mining and strip mining technologies for deep coal mining,taking the No.630 mining area with a depth of one kilometer in a certain mine as the research object,the parameters of surface movement angle,subsidence speed,and probability integration method were obtained based on measured data.The research results indi-cate that the range of surface hazards and the degree of surface movement and deformation caused by longwall mining are significantly greater than those caused by strip mining.As the mining degree increases,the subsidence coefficient and the tangent angle of the main impact gradually increase,and the degree of mining impact shows an increasingly obvious trend.关键词
