铁路煤矿采空区综合物探技术研究

The Research of Comprehensive Geophysical Technology in Railway Coal Mine Goaf Exploration

研究目的:结合我院近年来对采空区的勘察经验,对采空区综合物探方法进行系统的讨论和总结,提出铁路采空区综合物探工作模式,以有效指导今后的采空区勘察工作,优选适宜的综合物探技术,发挥其高效、经济等技术优势,提高地质勘查精度,为高风险采空地区铁路设计和施工安全提供重要支撑。研究结论:(1)工程物探现已成为解决采空区铁路工程地质问题的首选技术,在调查基础上,对疑似采空区路段物探工作,可用物探结果指导钻探布置;(2)通过研究总结,提出了综合考虑地形、采空区埋深及物探方法适宜性等条件下的采空区勘察综合物探模式;(3)勘察中优选适宜的综合物探技术,清晰揭示了采空区的不良地质体;(4)本研究成果可为采空区铁路、公路、工民建勘察设计提供借鉴。

Research purposes： Combining our exploratory experience which adopts the coal goaf in recent years,this paper carries on systematic discussion and summary in the goaf comprehensive physical prospecting method,proposes the model of railway comprehensive geophysical prospecting coal goaf,in order to effectively guide the coal goaf prospecting work in the future,select the suitable comprehensive geophysical prospecting technology,produce such technological advantages as its high- efficient,economy and so on,improve geologic prospect precision,to offer important support for design and construction safety of railway in high- risk goaf area.Research conclusions：（ 1） Engineering geophysical exploration has already become the first- selected technology which solved the geological problem of goaf in railway prospection now,on the basis of investigating,for the geophysical prospecting of highway section in suspected to be goaf,instruct drilling and assigning with the geophysical prospecting result.（ 2） Through summarizing and studying,propose the comprehensive physical prospecting way considering the topography,the depth of goaf and geophysical prospecting method suitable,etc.（ 3） Select the suitable comprehensive geophysical prospecting technology,announc clearly the harmful geological body while reconnoitring.（ 4） This research results can offer reference to reconnoitre and design the goaf railway,highway,civil engineering.
