二维地震勘探技术在采空区勘探中的应用研究

Research on the Application of Two-dimensional Seismic Exploration Technology in Goaf Exploration

为验证焦作市和祥小区采空区场地建筑物地基基础是否满足建设要求,人们利用地震探测了解该采空区上覆地层岩土体起伏形态和构造发育情况。本文建立三种模型正演煤矿采空区地震反射波波形特征,探明该采空区面积、空隙深度、采空区容积量,为该采空区场地上建筑物的安全建设提供有效的指导。

In order to verify whether the foundations of buildings in the mined-out area of Jiaozuo City and Xiang district meet the construction requirements,people use seismic exploration to understand the undulating shape and structural development of the overlying rock and soil in the mined-out area.This paper establishes three models for forward modeling of the seismic reflection wave characteristics of the goaf of coal mines,and proves the area,depth of voids and volume of the goaf,and provides effective guidance for the safe construction of buildings on the goaf site.
