深部矿井工作面地质条件及其地球物理勘探技术

Geological conditions and other geophysical survey technologies of coal mining face in deep mine

矿井深部延拓是解决我国东部煤田资源紧张的必然途径,深部开采中地质构造、矿井水、煤层瓦斯和顶底板条件等是矿井生产的主要致灾地质因素。分析论述了当前煤田地球物理勘探主要技术方法的应用状况及特点,指出多波多分量地震勘探、矿井高密度直流电法、矿井瞬变电磁法及地质雷达等新技术方法及其综合应用将在深部矿井致灾地质因素预测预报中发挥重要作用。

The mine deepening development is the necessary access to solve the tension of the coalfield resources in the east part of China. In deep mining operation, the geological structure, mine water, seam gas and, roof and floor condition are the main geological factors to cause the disasters to the mine safety production, The paper analyzed the application status and features of the main technical methods for the geophysical survey of coal field. The paper pointed that the multi - wave multi - components seismic survey, mine high density DC method, mine transient electromagnetic method and geological radar, and other new technical method, as well as the comprehensive application would play an important role to forecast and predict the geological factors cause mine disasters in deep mine.
