Abstract 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.
