综采工作面过陷落柱防治及其对策

Water Prevention and Control of Fully Mechanized Working Face Passing a Collapse Column and Its Countermeasures

掘进过程中揭露的岩溶陷落柱,通过物、钻探圈定柱体分布范围、延伸深度,进行水文地质分析确定为不导水柱体,据此提出不导水岩溶陷落柱防治措施,确保综采工作安全生产。

Karst collapse column exposed in the process of excavation can be defined as non water - conducted collapse column through the distribution range and elongated depth judged by means of geophysical and drilling prospecting and hydrogeology analysis, which on the basis of, this paper puts forward the controlling measures for non water -conducted karst collapse column, to ensure fully mechanized work safety in production.
