1.绪言 对于煤系中断层构造的了解,有助于采矿工作者布置工作面。近年来由于采煤工作面投资大大增加,若中断生产,则对经济损失很大,故对这种情况的了解就越来越迫切了。 常用的探查地层的各种地球物理方法只能识别主要断层面,但是有两种地球物理勘探方法在井下的应用却是有希望的。 第一种方法是地震透射法,是西德埃森的采矿顾问博格斯提出与发展的,并于1965
1. INTRODUCTION Knowledge of the structure of coal-bearing faults can help miners to arrange work surfaces. In recent years, the coal mining face greatly increased investment, if the interruption of production, then a great economic loss, so the understanding of this situation more and more urgent. Geophysical methods commonly used to explore the formation can only identify the main fault plane, but there are two kinds of geophysical exploration methods in the underground is promising. The first method, the Seismic Transmission Method, was proposed and developed by Boggs, a mining consultant in West-Essen, and developed in 1965
