在矿区工程地质勘探中,获取深部基岩的物理力学参数的方法往往比较单一,一般通过野外钻探采样返回实验室进行岩石试验来获得。全波列测井是一种较好的原位测井方法,通过声波探头在井内的激发、接收来获取深部基岩波速值,根据公式计算岩体的物理力学参数。本文通过介绍全波列测井设备、操作过程及软件处理方法以及对SICOMINES矿区GK02号钻孔的全波列测井曲线分析,总结了全波列测井资料处理方法和试验结果在矿区工程地质勘探中的重要性,并通过与室内试验和钻探岩芯的比较,更好地查清了矿区边坡中的软弱层,为矿区进行工程地质岩组划分与边坡计算提供了重要依据。
In the engineering geological exploration of mining area, the method of obtaining the physical and mechanical parameters of deep bedrock is often relatively simple, which is usually obtained through the field test of rock drilling returned to the laboratory. Full-wave logging is a good in-situ logging method. The wave velocities of deep bedrock can be obtained by the excitation and reception of the acoustic probe in the well, and the physical and mechanical parameters of the rock mass can be calculated according to the formula. In this paper, by introducing the full-wave logging equipment, operation process and software processing methods as well as the full-wave logging curve analysis of GK02 borehole in the SICOMINES mine area, this paper summarizes the data processing methods and results of the full-wave column logging in the engineering geology The importance of exploration and the comparison with laboratory tests and drilling cores to better identify the weak layers in the mining slope and provide an important basis for the division of engineering geology and rock group and slope calculation.
