三维地震动态解释在淮北构造复杂煤矿生产中的应用

Application of 3D Seismic Dynamic Interpretation in the Production of Structurally Complex Coal Mines in Huaibei

三维地震勘探技术在煤矿安全高效矿井地质保障系统中发挥着重要的作用,淮北矿区构造复杂,断层密度大,断层已成为严重制约淮北矿区采区接替和增储保供的主要因素。本文将三维地震动态解释应用于淮北构造复杂煤矿的生产中,在煤矿工作面设计、巷道掘进和工作面贯通等多个生产阶段开展地震动态解释,针对大巷掘进过程中地质保障的实际需求开展了地震动态解释工作。应用实践表明,煤矿工作面生产过程中的地震动态解释工作将分析对象限定为一个工作面、一条巷道甚至一条断层,研究对象更聚焦,更精准,且时效性强,能够为煤矿工作面生产过程提供较为准确的指导,助力煤矿安全高效开采。

The 3D seismic exploration technology plays an important role in the safe and efficient mine geological guarantee system of coal mines.The Huaibei mine area has complex structures and high fault density,and faults are already become the main factor that seriously restricts the replacement and increase of reserves and guarantee of supply in the mining area of Huaibei mine area.This article applies 3D seismic dynamic interpretation to the production of structurally complex coal mines in Huaibei.Seismic dynamic interpretation is carried out in multiple production stages such as coal mine working face design,roadway excavation,working face connectivity and etc.In view of the actual demand of geological guarantee in the process of the main roadway excavation,the seismic dynamic interpretation work is carried out.The application practice shows that the seismic dynamic interpretation work in the production process of coal mine working faces limits the analysis object to a working face,a roadway,or even a fault.The research object is more focused,precise,and has strong timeliness,which can provide more accurate guidance for the production process of coal mine working faces and assist in safe and efficient mining of coal mines.
