Description
Field of the Invention
The present disclosure belongs to the field of rock mineral content testing, and specifically relates to
a TBM (Tunnel Boring Machine)-mounted rock quartz content testing system and method.
Background of the Invention
The statement of this section merely provides background art information related to the present
disclosure, and does not necessarily constitute the prior art.
At present, most of the deep and long tunnels of traffic engineering, hydraulic engineering and
mining engineering under construction and proposed have a length-diameter ratio of 600 to 1000 or
even higher. Under this condition, a full face Tunnel Boring Machine (TBM) construction method is
internationally recognized, with the advantages of high excavation speed, small construction
disturbance, high hole quality, high comprehensive economic and social benefits, etc. However,
when excavating in hard rock, a cutter often wears severely to cause the problems of decline in the
rock breaking performance of a cutter system, low excavation efficiency, etc., which seriously
affects the construction progress of TBM and then increases the construction cost. A lot of scholars
at home and abroad have found that quartz in the surrounding rock of tunnels is the main mineral
that affects the wear resistance of the rock and causes the TBM cutter wear. Therefore, the
understanding of the quartz content in tunnel excavation surrounding rock is of great significance
for predicting cutter wear and making intelligent decisions about TBM construction.
Quartz is a kind of mineral. At present, the main methods for identifying minerals include chemical
analysis, polarizing microscope analysis, near-infrared analysis, X-ray diffraction (XRD) analysis,
etc. Among them, the chemical analysis method has high accuracy, but has a long analysis period
and is uneconomical; the polarizing microscope analysis method needs to grind rock into slices and
then manually observe and analyze the slices under a polarizing microscope, so this method also
has a long analysis period and has high requirements for the level of analysis personnel; and the
near-infrared analysis method is fast and accurate, but it can only analyze some altered minerals and
cannot identify quartz.
An X-ray diffractometer uses the diffraction principle to accurately test the crystal structure of a
substance to be analyzed, so as to accurately perform phase analysis, qualitative analysis and
quantitative analysis. Minerals are naturally crystalline, so the X-ray diffraction method is currently
recognized as the most effective method for identifying minerals. This method has the advantages
of low sample demand, short analysis time, high accuracy in qualitative and quantitative analysis,
etc. However, this method can only test and analyze powder samples. Therefore, in order to use this
method to quickly test the quartz content in the surrounding rock during the TBM excavation
process, not only a portable XRD device with small size and high accuracy is required, but also a
series of problems need to be solved, such as how to mount the XRD device on a TBM, how to
process hard surrounding rock in a tunnel into rock powder and automatically import the rock
powder into a sample chamber of the XRD device, and how to automatically give the quartz content
analysis results of rock.

A TBM-mounted rock quartz content testing system, as shown in FIG. 1, includes a base 2, side
walls 3, a ceiling 4, a sampling device 5, a high-pressure water pump 6, a blower 7, an X-ray
diffraction device 8, and a computer data analysis system 9.
The base 2 is made of a stainless steel plate and has a rectangular outline, the side walls 3 are
welded vertically above the base, and the ceiling 4 is approximately arched and is also made of a
stainless steel plate. The protective device consisting of the base 2, the side walls 3 and the ceiling 4
can not only prevent falling rock, water seepage, etc. of a tunnel vault from damaging internal
instruments and components, but also can provide a support for other components of the system.
The sampling device 5 is mainly composed of a hydraulic arm, an improved impact drill, a powder
chamber, a high-pressure water supply system and a blower. As shown in FIG. 2, the hydraulic arm
is vertically welded on a left side wall, and the other end is connected to the impact drill. The
hydraulic arm 20 is telescopic to control the left and right movement of the impact drill and provide
thrust for the impact drill. The biggest difference between the improved impact drill and the existing
impact drill is that its front end is provided with a slot for installing the powder chamber, a spring
21 is arranged in the slot, and the left side of the powder chamber 22 is connected to the spring 21
in the slot. The powder chamber 21 is made of organic glass. A rubber ring 25 is installed at the front end of the powder chamber 22. When an impact drill bit is driven into the surrounding rock 30, the rubber ring 25 is closely attached to the surrounding rock to buffer and protect the front end of the powder chamber. There is a collecting hopper 23 at the middle lower part of the powder chamber 22, and rock powder cut by the impact drill is collected herein. A detachable screen 26 is installed under the collecting hopper 23, there are two discharge ports under the screen 26, one is a powder discharge port 28, the other is a waste discharge port 29, and each has a valve 27. There are two ports at the upper part of the powder chamber, one is a water outlet and the other is an air outlet.
The high-pressure water supply system 6 is installed at the water outlet to clean the powder
chamber 22, and the blower 7 is installed at the air outlet to blow out hot air for drying the powder
chamber and other auxiliary components.
The X-ray diffraction device is mainly an existing X-ray diffractometer, the sample chamber of
which is slightly improved in the present disclosure. As shown in FIG. 3, a funnel 31 with a hose 33
is added to the opening of the original sample chamber, and a micro oscillator 32 is installed at the
lower part of the funnel, so as to ensure that the rock powder from the powder discharge port can
enter the sample chamber smoothly.
A powder diffraction data set dedicated to the subject of minerals in a study area is added to the
computer data analysis system. The data set is screened out on the basis of the existing X-ray
diffraction reference standard spectra, i.e., PDF cards, which can reduce the time for checking the
PDF cards by the system and improve the accuracy of quartz content determination results.
The computer data analysis system can receive a rock powder diffraction pattern emitted by the
X-ray diffraction device through wireless transmission, perform automatic retrieval in the powder
diffraction data set dedicated to the subject of minerals in the study area in the system, and match
d-I/Io data acquired from the pattern with various mineral data in the powder diffraction data set, to
automatically interpret the quartz content in the rock powder.
A usage method of the TBM-mounted rock quartz content determination system, as shown in FIG. 4,
includes the following steps:
Step A: when a cutter of a TBM is working, a gripper shoe 1 of the TBM is closely attached to the
surrounding rock 30 to provide thrust force for the cutter of the TBM to cut the rock. At this time, the hydraulic arm 20 is started, so that a drill bit 24 of the impact drill is in contact with the surrounding rock 30. Meanwhile, the valve 27 at the powder discharge port is opened.
Step B: a switch of the impact drill is started, the hydraulic arm 20 is controlled to push the impact
drill slowly, and the drill bit 24 continuously drills into the surrounding rock 30. The drilled rock
powder continuously enters the powder chamber 22 and falls into the funnel 31 of the sample
chamber of the X-ray diffractometer from the screen 26 and the powder discharge port 28.
Step C: the micro-oscillator at the funnel of the sample chamber is started to ensure that the rock
powder in the funnel 31 can enter the sample chamber of the X-ray diffractometer. When the
amount of powder in a cavity 35 of the sample chamber meets the test requirement, the valve 27 at
the powder discharge port is closed, the impact drill is stopped, and the hydraulic arm 20 is
controlled to retract.
Step D: the X-ray diffraction device 8 is started to work. After about 5 minutes, a test pattern is
obtained and automatically transmitted to a computer. Then the data analysis system 9 in the
computer is opened, the collected pattern file is added to the data analysis system, and the system
automatically performs retrieval and matching and provides quartz content results and
corresponding pie charts after a few seconds.
Step E: the valve at the powder discharge port is closed, the valve at the waste discharge port is
opened, the screen 26 is removed, the high-pressure water supply system 6 is opened to spray
high-pressure water to clean the powder chamber 22, and then waste materials and water flow out
from the waste discharge port 29. After a few seconds, the high-pressure water supply system 6 is
closed and the blower 7 is turned on to dry the powder chamber 22. Then the valve at the waste
discharge port is closed and the valve at the powder discharge port is opened.
Step F: the screen and the sample chamber are replaced with new ones. After the TBM step is
changed, the quartz content determination of the next cycle can be performed.
