神府矿区隐蔽采空区相关致灾因素分析及勘查技术

本文在分析神府矿区隐蔽采空区相关致灾因素基础上,针对该区隐蔽采空区主要相关致灾因素特点进行了勘查方法重新划分,对各勘查技术方法测网密度、参数选择等进行优化,形成一套精细勘查神府矿区隐蔽采空区相关致灾地质因素的技术体系.为了充分发挥不同勘查方法对隐蔽采空区不同致灾因素响应特征的的优点,分别采用浅层地震技术勘查采空区范围、瞬变电磁法技术勘查积水区位置;采用同位素测氡技术和钻孔测温、测气技术勘查火区和有毒有害气体;采用钻孔电视技术和钻孔冲洗液漏失量观测技术勘查采空区顶板;采用三维激光扫描精确勘查房柱式采空区残留煤柱尺寸.该体系研究成果为神府矿区采空区隐蔽灾害评估、治理提供参考依据.

Analysis of disaster-causing factors and exploration techniques in concealed mined areas in Shenfu mining area

Based on the analysis of the related hazard factors in the concealed goaf in Shenfu mining area,this paper re-divides the exploration methods for the characteristics of the main related hazard factors in the concealed goaf in this area,and conducts surveying techniques such as measuring network density and parameter selection.Optimization,to form a set of technical systems for the detailed exploration of the geological factors related to the disasters in the Shenfu mining area.In order to give full play to the different advantages of different exploration methods for different disaster response factors in concealed mined areas,shallow seismic techniques were used to explore the extent of goafs and transient electromagnetic techniques to explore the location of the stagnant water area;And drilling temperature measurement,gas measurement technology to explore the fire area and toxic and harmful gases;using the drilling TV technology and drilling rinsing fluid loss observation technology to explore the goaf roof;using 3D laser scanning to accurately survey the residue pillar size of the room-type goaf.The research results of this system provide reference for the assessment and treatment of hidden disasters in the goaf of Shenfu mining area.
