摘要:
采空区勘察是铁路工程地质选线的重要组成部分,采空区具有危害性大、隐蔽性强、既有资料准确性参差不齐等特点。在陡倾岩层的勘察中,斜孔勘探可与产状倾向大角度相交针对性布置钻孔,且相同孔深可揭示更多地层以相互印证,具有明显的靶向勘察优势。目前,斜孔勘探用于铁路采空区勘察的案例较少,本文以西渝高速铁路铁峰山越岭段采空区勘探为工程背景,在收集分析矿区资料和进行详细地质调绘的基础上,采用斜孔勘探对煤矿采空区进行勘察,为线路走向及标高选择提供了明确的依据,起到了良好的效果。
Abstract:
Goaf investigation is an important part of geological assessment for route selection of railway. The goaf features great hazards, high concealment, and accuracy of existing data varying significantly. For the inclined hole exploration, in the investigation of steeply inclined rock strata, boreholes can be arranged in a targeted manner by intersecting with the occurrence tendency at a large angle; and for the same hole depth, more strata can be revealed to realize the mutual corroboration, resulting in obvious advantages of targeted investigation. At present, there are few cases of applying inclined hole exploration for the investigation of the railway goaf. In this paper, the goaf investigation of the Tiefengshan mountain-crossing section of Xi’an-Chongqing High-speed Railway is taken as a case for study. Based on an analysis on the collected mining area data and detailed geological surveying and mapping, the inclined hole exploration is used to investigate the coal mine goaf, providing a clear basis for the selection of line alignment and elevation, and resulting in good effects.
