Detailed Description
Referring now to the drawings in the specification, in conjunction with specific embodiments, there is illustrated the following: a mining microseism monitoring system, including monitoring unit 1, receive stock 2, inflation location portion 5 and positioner 4. The main hardware of the monitoring unit 1 is a sensor, a data acquisition unit, a time synchronization unit, a data communication unit, a server and the like, and the detailed structure of the monitoring unit can refer to the mining micro-seismic detection equipment in the prior art. The probe of the monitoring unit 1 is connected with a receiving anchor rod 2, and the receiving anchor rod 2 is inserted in a drilling hole 7 of a rock body 6. The receiving anchor rod 2 is of a hollow structure, the inner cavity of the receiving anchor rod is a grouting cavity, and a plurality of grouting holes 3 communicated with the grouting cavity are formed in the receiving anchor rod 2. Upper portion cover of receipt stock 2 be equipped with gliding positioner 4 from top to bottom, positioner 4 is including circular location portion 10 and positioning baffle 11, circular location portion 10 can adopt circular slider or circular pipe, and the diameter of circular location portion 10 is corresponding with the aperture of drilling 7, positioning baffle 11's overall dimension then is greater than the aperture of drilling 7, circular location portion 10's top body coupling positioning baffle 11 to constitute positioner 4, positioner 4 locates the upper portion position department of receiving stock 2 through central through-hole cover. The bottom end of the receiving anchor rod 2 is provided with an expansion positioning part 5, and the expansion positioning part 5 is of an oval structure with a hollow interior. The upper part of the receiving anchor rod 2, namely the upper part of the positioning device 4, is connected with a grouting pipe 9, and the grouting pipe 9 is connected with external grouting equipment.
