Abstract
The invention discloses a mining coal wall pickup sensor and a mounting method for the same. The mining coal wall pickup sensor comprises a sensor mounting part, a sensor fixing part and a sensor, wherein the sensor mounting part adopts a sensor mounting rod; the sensor fixing part is provided with an injection rod, a resin anchoring agent, a screw and a paper cup. According to the mining coal wall pickup sensor and the mounting method for the same, the injected resin anchoring agent is combined for the mounting of the mining coal wall pickup sensor, and by such a design, the condition of poor quality of a signal received by the sensor mounted on an anchor rod or an anchor rope can be avoided, the sensor mounted by the method is high in received signal quality, free of distortion, convenient to mount and easy to recover, time-space parameters of a micro-earthquake source can be accurately controlled, and the aim of accurate positioning is fulfilled.
Description
Technical field:
The present invention relates to the installation of sensor, a kind of mining Microseismic monitoring system rib picks up shake sensor and installation method thereof specifically.
Background technology:
Due to the attendant phenomenon that microearthquake is coal petrography material deformation, crack initiation and expansion process, the mechanical behavior of it and lithostructure has close correlativity, obviously, a large amount of destruction about force-bearing of surrounding rock mass and the useful information of Geological Defects reactivation process is contained in microearthquake signal, this can infer the mechanical behavior of coal petrography material, whether prediction surrounding rock structure destroys.Sensor is most important as source itself and the effective coupling scheme of coal and rock of Microseismic monitoring system signal, and this patent adopts injection-type resin anchoring agent for the coupling of the sensor that punches.
What generally adopt at present is fixed on punching mounting means etc. on down-hole anchor pole or anchor cable, general, there is acknowledge(ment) signal difference, installs the problems such as complicated, recovery utilization rate is low, directly has influence on that state event location precision is low, system operation cost is high.
Summary of the invention:
The technical problem to be solved in the present invention is: in order to overcome Problems existing in appeal, provide the coupling of a kind of injection-type resin anchoring agent for sensor, sensor adopts punching mounting means, and it can accept acoustical signal that microearthquake brings out efficiently, it is convenient to install, easily reclaim.
In order to solve above-mentioned existing technical matters, the present invention by the following technical solutions: a kind of mining rib picks up shake sensor, and it includes sensor mounting portion and sensor fixed part, sensor; The sensor mounting portion employing told and the sensor mounting rod of sensor, the sensor fixed part told injects bar, resin anchoring agent, screw, dixie cup.
Mining rib picks up an installation method for shake sensor,
1) sensor mounting rod is used for rib, the requirement according to hole depth increases sensor mounting rod, and sensor is installed and adopted sensing mounting rod to be advanced at the bottom of hole by sensor, sensor is advanced at the bottom of hole and fully contacts with rib;
2) resin anchoring agent is used for the installation of mining rib sensor, told inject bar resin anchoring agent is pushed at the bottom of hole be used for sensor and rib to be fully coupled between rib, described screw is the intermediate medium of sensor and resin anchoring agent, and dixie cup is used for sensor and resin anchoring agent to keep apart so that reclaim.
Described sensor adopts punching mounting means, and hole becomes 30 degree, the vertical rib elevation angle.
Sensor and dixie cup are fixed by screw by described Sensor tail, inject bar and are pushed in dixie cup by resin anchoring agent.
Rib installs a sensor every 150m.
Principle of work of the present invention is as follows: this device adopts punching mounting means, mounting hole becomes 30 degree, the vertical rib elevation angle, sensor is advanced at the bottom of hole by sensing mounting rod by sensor peace, sensor is advanced at the bottom of hole fully to contact with rib, sensor and dixie cup are fixed by screw by Sensor tail, injecting bar is pushed in dixie cup by resin anchoring agent, and withstand mounting rod certain hour resin anchoring agent is fully contacted with rib or rock wall, rib installs a sensor every 150m.
The installation of this sensor, arrange the sensor of some quantity with certain net degree around focus, composition sensor three-dimensional geometry array, when there is micro-seismic event in monitoring range, sensor can accept microseismic signals, and this acoustical signal is converted to voltage signal, be transferred to micro seismic monitoring instrument main frame by shielding communication cable.Measure by Multipoint synchronous data acquisition the moment that each sensor receives this signal, together with each sensor coordinates and survey velocity of wave substitute into solving equations, the Time And Space Parameters of microquake sources can be determined, reach pinpoint object.
Beneficial effect of the present invention: the described installation being used for mining rib sensor in conjunction with injection-type resin anchoring agent, adopt this kind of design that sensor can be avoided to be arranged on the poor signal quality that anchor pole or anchor cable accept, this kind install accept signal quality good, undistorted, install convenient, easily reclaim, accurately can control the Time And Space Parameters of microquake sources, reach pinpoint object.
