综合物探技术在矿井陷落柱识别的应用研究

陷落柱作为矿井隐蔽致灾体之一,常常表现为由下伏的灰岩坍陷形成,一定规模的陷落柱是矿井重要的导水通道,成为制约矿井自动化开采和矿井安全生产的重要因素。为安全、高效预测矿井井田内的陷落柱的空间分布特征,常采用综合地球物理勘探技术提高探测的精确度和精准度。本文采用地面三维地震勘探技术与对面可控源大地音频测深(CSAMT)技术,对梧桐庄矿井六采区进行综合探测、数据处理与综合解释研究。结果表明,三维地震勘探技术能有效识别矿井井下小构造,陷落柱的规模、空间形态,结合CSAMT的探测对陷落柱的含水性、含水量进一步得到验证,综合物探技术解决了矿井陷落柱的空间参数和富水状态,为下一步的综合处理提供有利的地质保障。

Study on comprehensive geophysical prospecting technologyin mine collapse column identification

As one of the hidden disaster causing bodies,the collapse column is often formed by the underlying limestone.The collapse column of a certain scale is an important water channel of the mine,and becomes an important factor restricting the automatic mining and safety production of the mine.In order to safely and efficiently predict the spatial distribution characteristics of collapse column in mine field,comprehensive geophysical exploration technology are often used to improve the detection accuracy and accuracy.In this paper,three-dimensional seismic exploration technology and CSAMT technology were used to study the comprehensive detection,data processing and comprehensive interpretation of No 6 mining area in Wutongzhuang coal mine.The results showed that the 3D seismic exploration technology can effectively identify the small structure in the mine,the scale and spatial form of the collapse column.Combined with the detection of CSAMT,the water content of the collapse column were further verified.The comprehensive geophysical exploration technology solved the spatial parameters and water rich state of the collapse column,and provided favorable geological guarantee for the next comprehensive treatment.
