摘要
以刘桥一矿首个综采工作面安全通过A9陷落柱为例,充分证明基于对陷落柱进行多角度探查、分析、评价的基础上,并采取有效的安全技术措施后是有可能实现安全回采的。
Using first fully mechanized working face of Liuqiaoyi Mine passing A9 collapse column safely as an example, it fully proves that on the basis of multi-angle probing, analysing and estimating collapse column, and taking effective safety technical measures is possible to realize safety mining.
