Abstract
A method for erecting transducer to monitor micro shock of deep hole in the pit at coal mine includes drilling monitor hole in 50m depth at tunnel in the pit, making open at half top of side wall on solid state bag with diameter less than that of drilled hole, sewing mother belt of nylon Velcro to form cement paste bag, packing cement paste bag into solid state bag to form double cement paste bag, drawing said bag into drilled hole to be at preset position, opening solid state bag quickly to seal monitor transducer in drilled hole when cement paste is solidified.
Description
Technical field
The application relates to coal mine downhole safety monitoring, especially micro seismic monitoring.
Background technology
The microseism position monitor technology that rock mass breaks is a mine safety monitoring technology advanced in the world today, can be widely used in prediction and forecast roof falling over great extent, prominent watered-out well, coal and mine disasters such as gas is outstanding, bump.At present the colliery of the mine degree of depth more shallow (in 450m) is when carrying out this work, and generally adopting faces down on ground drills, and with grouting three-component geophone micro seismic monitoring device is cast in the boring then, and the usefulness cable is connected with ground.When surpassing in the mine of 450m in the degree of depth in this way, obviously uneconomical when adopting said method, nor easy to operate.
Summary of the invention
The application's purpose is a kind of mounting method that is suitable for the microseismic monitoring sensor of coal mine deep well up-hole of invention.
The application's method is:
1, the underworkings in the needs monitoring bores monitoring holes from bottom to top, and the monitoring hole depth surpasses 50m;
2, solid state bag of processing less than bore diameter, at the sidewall first half opening of solid state bag, the master tape of nylon sticking belt is gone up in the opening part sewing;
3, will load onto microseismic monitoring sensor and cement paste is made into grout bag in the sack of a diameter greater than boring;
4, grout bag is packed in the solid state bag, go up solid state bag with the subband sealing of nylon sticking belt, fasten out the button rope on the subband of nylon sticking belt, the double-deck grout bag lifting rope of fastening suitable for reading becomes a double-deck grout bag;
5, anchor fluke that has fixed pulley of processing passes the grout bag lifting rope on the fixed pulley, with pole anchor fluke is incorporated into the hole at the bottom of, be fixed at the bottom of the hole;
6, then by manually progressively firmly drawing lifting rope, double-deck grout bag is drawn in the boring, whenever drawn in certain depth, fasten next double-deck grout bag again with lifting rope and continue to draw in the boring;
7, after traction arrives the precalculated position, the button of opening on the nylon sticking belt subband on the pulling solid state bag is restricted, and makes the solid state bag opening, and the grout bag of ot-yet-hardened is sagging naturally by gravity, is expanded to drill hole wall to contact;
8, stay cord is fastened on fixture, treat that cement grout solidifies the back microseismic monitoring sensor and firmly is enclosed in the boring.
Above-mentioned nylon sticking belt also is VELCRO, is the popular call of double buckle.Be exactly a kind of connection auxiliary material commonly used on the clothes, divide the primary and secondary two sides, one side is the fiber of small, flexible, and another side is the thing of the harder little Mao of picture pawl.
Mounting method of the present invention is applicable to that the soft stratum (it is yielding to hole) and the degree of depth surpass the boring of 50m.
Points for attention during installation:
1, to install as early as possible after boring is up to, prevent the boring distortion;
When 2, holing incompetent bed, the location, hole of collapsing will add sleeve pipe, and the anchor fluke rear portion adds guide peg, otherwise anchor fluke enters easily and collapses the hole, hole and can't install;
3, stay cord and opening rope can not relax in promoting distraction procedure, prevent that two ropes tangle knot, cause and can't promote;
Good effect of the present invention is: the present invention provides a kind of conveniently mounting method for microseismic monitoring sensor under the coal mine dark more than 50 meters.Sensor fully is coupled with the rock of drill hole wall and contacts in addition, prevents the decay of microseismic signals in the hole, helps the reception of signal, the reliability height.Not only solved deep-well surface drilling complicated operation, problem that expense is high, and can apply in fields such as water conservancy, ground, tunnels.

Marginal data: at the bottom of 1-hole, 2-anchor fluke, 3-nylon sticking belt, 4-cement grout, 5-microseismic monitoring sensor, 6-signal cable, 7-next grout bag, 8-iron hoop, 9-fixed pulley, 10-lifting rope, 11-solid state bag, 12-grout bag, 13-open button to restrict, 14-rock, 15-boring.
The specific embodiment
Describe mounting method of the present invention in detail according to Fig. 1 below.
1, the underworkings in the needs monitoring bores monitoring holes 15 from bottom to top, and 15 hole depths of holing surpass 50m;
2, solid state bag 11 of processing less than bore diameter, at the sidewall first half opening of solid state bag 11, the master tape of nylon sticking belt 3 is gone up in the opening part sewing;
3, will load onto microseismic monitoring sensor 5 in the sack of a diameter greater than bore diameter and cement grout 4 is made into cement paste 12;
4, grout bag 12 is packed in the solid state bag 11, solid state bag 11 is gone up in subband sealing with nylon sticking belt 3, fasten out button rope 13 on the subband of nylon sticking belt 3, double-deck grout bag 12 lifting ropes 10 of fastening suitable for reading, become a double-deck grout bag 12, the signal cable 6 of sensor exposes from the end opening of double-deck grout bag 12;
5, the anchor fluke 2 of a band fixed pulley of processing passes the lifting rope 10 of grout bag 12 on the fixed pulley, with pole anchor fluke 2 is headed at the bottom of the hole 1, is fixed at the bottom of the hole in 1;
6, then by manually progressively firmly drawing lifting rope 10, double-deck grout bag 12 is drawn in the boring 15, whenever drawn in certain depth, fasten next double-deck grout bag 7 again with lifting rope 10 and continue to draw in the boring 15;
7, after traction arrives the precalculated position, opening button rope 13 on nylon sticking belt 3 subbands on the pulling solid state bag 11, make solid state bag 11 openings, the grout bag 12 of ot-yet-hardened is sagging naturally by gravity, is expanded to 15 the hole wall of holing to contact;
8, will hang 10 ropes and fasten on fixture, treat that cement grout solidifies the back microseismic monitoring sensor and firmly is enclosed in the boring.
