摘要
采空区密闭墙的砌筑位置及所用材料,对密闭墙的质量有重要影响,应根据支承压力的分布情况确定建墙位置。密闭墙的结构应采用柔性支护方式。
The building point and the material of airproof wall in the extracted face influnces the quality of airproof wall greatly. The point building wall must be determined according to the distribution of a support pressure.The structure of airproof wall must be yieldable.
