摘要
根据薛村矿东风井煤柱的位置及地表建筑情况，提出了风井煤柱的充填开采方案。通过地表移动和变形预计分析，结合地表建筑和设施的受损等级标准，对充填开采的安全性进行了分析。结果表明，充填开采引起的风井地表移动与变形很小，对风井地表建筑的影响极轻微，充填开采是安全可行的。风井煤柱充填开采采出7?2万t的风井压煤，具有明显的经济效益、社会效益。
Abstract
According to the location of air shaft coal pillar and the situation of surface buildings, a backfill mining scheme of air shaft pillar is proposed. Through surface movement and deformation prediction analysis, the security of backfill mining are analyzed with the damaged grading standard of surface buildings and facilities. The results indicate that the surface movement and deformation of air shaft caused by backfill mining is small and there is a slight influence of the surface buildings. Backfill mining is safe and feasible. 72000 tons of air shaft coal are mined offering obvious economic and social benefits.
