神府矿区突水溃砂地质灾害研究

STUDY ON GEOLOGICAL HARM OF BLOUING OUT WATER AND BURSTING SAMD IN SHEN FU COOL MINING AREA

针对神府矿区威肋安全生产的最大地质灾害──突水溃砂，本文通过实例，结合勘察成果，对其地质背景形成机理进行了总结分析，认为解决这一地质灾害目前最有效的措施是采前疏排基岩顶部直接充水含水层中地下水，使砂失去地下水载体而无法进入矿井。

Blowing out water and bursting sand is the biggest geological harm effecting safety produc-tion in shen Fu coal miningarell.The geological background and forming mechanism have been summa-rized and analysed through combining examples with exploration results,It is believed that the mosteffective measure resolving this kind geological harm is draining underground water in fill-directedwateraquifer upper bed rock before mining,resulting to lost sand carrier to come into mine.
