Description

TBM搭载式岩石石英含量测定***及其方法TBM mounted rock quartz content determination system and method 技术领域Technical field
本公开属于岩土含量测定领域，具体涉及一种TBM搭载式岩石石英含量测定***及其方法。The present disclosure belongs to the field of rock and soil content determination, and specifically relates to a TBM-mounted rock quartz content determination system and method.
背景技术Background technique
本部分的陈述仅仅是提供了与本公开相关的背景技术信息，不必然构成在先技术。The statements in this section merely provide background information related to the present disclosure, and do not necessarily constitute prior art.
目前在建和拟建的绝大多数交通、水工深长隧洞和矿山深井巷道，其长径比达到600～1000甚至更高，在此条件下，国际上公认采用全断面隧道掘进机(Tunnel Boring Machine，TBM)工法施工，该方法具有掘进速度快、施工扰动小、成洞质量高、综合经济社会效益高等优势。但在硬岩中掘进时，常会遭遇刀盘磨损严重进而导致刀盘***破岩性能下降、掘进效率低下等问题，严重影响了TBM的施工进度，进而增加了施工成本。经国内外大量学者研究发现，隧道围岩中的石英是影响岩石耐磨性和导致TBM刀盘磨损的主要矿物，因此通过了解隧道开挖围岩中的石英含量，对预测刀盘磨损以及TBM施工智能决策具有重要意义。At present, most of the traffic, hydraulic deep and long tunnels and deep mine tunnels under construction and proposed to be constructed have a length-to-diameter ratio of 600 to 1000 or even higher. Under this condition, it is recognized internationally that full-face tunnel boring machines (Tunnel Boring Machines) are used. Machine, TBM) construction method, this method has the advantages of fast excavation speed, small construction disturbance, high quality of hole formation, and high comprehensive economic and social benefits. However, when tunneling in hard rock, severe wear of the cutter head is often encountered, which leads to a decrease in the breaking performance of the cutter head system and low tunneling efficiency, which seriously affects the construction progress of TBM and increases the construction cost. A large number of scholars at home and abroad have found that the quartz in the surrounding rock of the tunnel is the main mineral that affects the wear resistance of the rock and causes the wear of the TBM cutter head. Therefore, by understanding the quartz content in the surrounding rock of the tunnel excavation, it is useful to predict the wear of the cutter head and the TBM. Intelligent decision-making for construction is of great significance.
石英是矿物的一种，目前鉴定和识别矿物的主要方法有化学分析、偏光显微镜分析、近红外分析、X射线衍射分析等。其中化学分析虽准确度高，但分析周期长、不经济；偏光显微镜分析需先将岩石磨成薄片，然后再通过人工在偏光显微镜下对薄片进行观察分析，该方法同样分析周期长且对分析人员水平要 求较高；近红外分析速度快且准确度较高，但只能对一些蚀变矿物进行分析而无法识别石英。Quartz is a kind of minerals. At present, the main methods for identifying and identifying minerals include chemical analysis, polarization microscope analysis, near-infrared analysis, and X-ray diffraction analysis. Although chemical analysis has high accuracy, it has a long analysis period and is uneconomical. Polarized light microscope analysis needs to grind the rock into thin slices, and then manually observe and analyze the thin slices under the polarized light microscope. This method also has a long analysis period and has a long analysis period. Personnel requirements are high; near-infrared analysis is fast and accurate, but it can only analyze some altered minerals and cannot identify quartz.
X射线衍射仪是利用衍射原理，精确测定待分析物质的晶体结构，从而精确的进行物相分析、定性分析和定量分析。矿物是天然结晶态，因此X射线衍射法是目前公认的最有效的矿物鉴定方法，该方法具有需要样品量少、分析时间短且在定性和定量分析方面精度高等优点。但该方法只能对粉末样品进行测试分析，因此要想在TBM掘进过程中使用该方法对围岩中石英含量进行快速测定，不仅需要有体积小且精度高的便携式XRD设备，还要解决如何将XRD设备搭载在TBM上、如何将隧道围岩坚硬岩石处理成岩石粉末并自动导入XRD设备样品舱中、如何自动化给出岩石石英含量分析结果等一系列问题。The X-ray diffractometer uses the principle of diffraction to accurately determine the crystal structure of the substance to be analyzed, thereby accurately performing phase analysis, qualitative analysis and quantitative analysis. Minerals are naturally crystalline, so X-ray diffraction is currently recognized as the most effective method for mineral identification. This method has the advantages of requiring a small amount of sample, short analysis time, and high accuracy in qualitative and quantitative analysis. However, this method can only test and analyze powder samples. Therefore, in order to use this method to quickly determine the content of quartz in the surrounding rock during TBM tunnelling, it is not only necessary to have a small and high-precision portable XRD device, but also how to solve the problem. Mount XRD equipment on the TBM, how to process the hard rock of the tunnel surrounding rock into rock powder and automatically import it into the XRD equipment sample compartment, and how to automatically give the rock quartz content analysis results.
