复杂地质条件回采面多手段综合物探技术应用与成果分析

Application and result analysis of multi-means comprehensive geophysical detection technology in working face with complex geological condition

由于矿井地质条件复杂多变、施工过程中客观干扰因素不可排除等原因,造成了物探成果误报率高、准确率低的问题,尤其是对地质构造相对复杂区域的探测,单一物探技术手段很难达到良好的探测效果。为了有效解决该问题,须利用综合物探技术手段开展精准物探、透明地质工作。本文以霍州煤电集团亿隆煤业1-105工作面为例,在该回采工作面进行无线电坑透、瞬变电磁、音频电透视以及直流电法测深,并对4种物探方法的综合成果进行分析研究,表明井下多手段综合物探联合分析解释能有效提高构造及水害预测预报的准确率,提高探测准确性。

Due to the complex and changeable geological conditions of the mine and the non-exclusion of objective interference factors in the construction process,the problems of high false alarm rate and low accuracy of geophysical detection results are caused.Especially for the detection of relatively complex geological structures,it is difficult to achieve good detection results by single geophysical detection technology.In order to effectively solve this problem,it is necessary to use comprehensive geophysical detection technology to carry out accurate geophysical detection and transparent geology work.In this paper,the No.1-105 face of Yilong Coal Industry of Huozhou Coal and Electricity Group was taken as an example.Radio wave tunnel perspective,transient electromagnetism,audio electrical perspective and direct current method exploring depth were carried out in this working face,and the comprehensive results of four geophysical detection methods were analyzed and studied.It showed that the combined analysis and interpretation of underground multi-means comprehensive geophysical detection could effectively improve the accuracy of structure and water damage prediction and improve the accuracy of detection.
