软岩矿区井下测井技术发展及其应用

Application and development of underground logging technology in soft rock mine

基于开滦矿区软岩的地质特点,对该矿区多年来钻孔窥视仪、全方位测斜仪、全景成像仪和综合测井分析仪等测井技术在地质探测中的应用经验进行分析,介绍了测井技术现状及开滦煤矿在井下测井工作的开展应用情况。随着技术的发展和进步,井下测井技术由最初的单一试验性测井向目前的综合性应用性测井发展,有效解决超前探测、老空水探放、岩层微观分析等安全生产方面的疑难问题,弥补了常规钻探的不足,该技术已经成为煤矿复杂地质问题分析的一种重要手段。

Based on the soft rock geological features of Kailuan Mining area and the logging technology of drilling observation equipment, omnibearing inclinometer, panoramic imager and logging analyzer, the current mine logging technology of Kailuan Group was introduced. The logging technology evolved from single test measurement to comprehensive logging technology, which solved the problem of advanced mining, goaf water release, microanalysis of rock formations and safe mining, made up the disadvantages of normal drilling, the technology has become an important mean to solve the complex geological problem.
