Abstract

A method for erecting transducer to monitor micro shock of deep well shallow hole in coal mine includes preparing hydraulic pillow, setting transducer in one side of hard plastic block with arc cross section and filling gel to fix it, binding another hard plastic block with arc cross section and hydraulic bag to be an integral unit, fixing an oil tube on hydraulic bag to form a monitoring unit, series-connecting said monitoring unit to be unit string by signal cable and drawing rope, placing unit in drilled hole at preset position to let hard plastic block be opened and pressed in drilled hole for monitoring micro shock.

Description

The mounting method of shallow hole microseismic monitoring sensor of coal mine deep well
Technical field
The present invention relates to the coal mine downhole safety monitoring, especially monitor the microseism position monitor that rock mass breaks.
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 is installed then, monitors main frame and is also placed in ground, and it is simple relatively to operate.At the mine of the degree of depth above 450m, adopt said method obviously uneconomical, nor easy to operate.Therefore, need a kind of method that is suitable for the installation three-component geophone of coal mine deep well down-hole in boring (degree of depth is less than 50m) of invention.
Summary of the invention
The objective of the invention is to invent a kind of mounting method that is suitable for the microseismic monitoring sensor of shallow bore hole under the coal mine deep well.
Method of the present invention is:
1, makes flat jack, the duroplasts piece that a section is an arc is processed the hole that can put into sensor from a side, placement upper sensor and encapsulating are fixed in the hole, be another section that duroplasts piece and a hydraulic pressure capsule of arc is bonded to an integral body again, fix an oil pipe on the hydraulic pressure capsule, become a monitoring device;
During use, monitoring device is serially connected by sensor signal cable and pull rope interval 10-25cm, forms the device string;
2, hole from bottom to top at the underworkings of needs monitoring;
3, will fix the fixed pulley anchor fluke and put on pull rope and head into the hole with drill steel at the bottom of;
4, then by artificial pulling traction rope, will install string and hang in the hole, be drawn to the precalculated position;
5, by hydraulic oil pipe to hydraulic pressure capsule pressurization oil transportation to the 2MPa, make it that two duroplasts pieces are strutted jam-packed in boring;
6, by signal cable the microseismic signals that receives is transferred to the main frame of data receiving center, carry out the microseism monitoring;
7, finish microseism monitoring after, open the pressure-relief valve of hydraulic tube, reclaim flat jack and reuse.
During being applicable to,, deepens micro seismic monitoring device mounting method of the present invention if hole firmly to use (drilling depth is in 50m) under the coal mine of mantlerock, the boring easy deformation, and flat jack is difficult to install and reclaim.Hydraulic pressure capsule in the flat jack with surrounding two hard plastic cover spreadings of the flat jack that bonds together of three-component geophone, squeezes on drill hole wall it when the pressure that is subjected to about 2MPa.
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, pull rope and stable rope can not relax in lifting process, prevent that two ropes tangle knot, cause and can't promote.
Good effect of the present invention is:
Mounting method of the present invention is convenient and swift, and sensor fully is coupled with the rock of drill hole wall and contacts, and prevents the decay of microseismic signals in the hole, helps the reception of signal, the reliability height.Solved in surface drilling complicated operation, problem that expense is high.Can apply in fields such as water conservancy, ground, tunnels.
Description of drawings
Fig. 1 is the vertical view of monitoring device of the present invention, and Fig. 2 is the front view of Fig. 1, and Fig. 3 is the mounting structure schematic diagram of the present invention in boring.
Among the figure: 1-duroplasts piece A, 2-hydraulic pressure capsule, 3-duroplasts piece B, 4-sensor, 5-glue, 6-hydraulic oil pipe, 7-cable rope, 8-anchor fluke, 9-fixed pulley, 10-monitoring device, 11-pull rope, 12-boring.
The specific embodiment
Narrate mounting method of the present invention below with reference to the accompanying drawings.
1, makes flat jack, the duroplasts piece 1 that a section is an arc is processed the hole that can put into sensor from a side, upward glue 5 is fixing to place upper sensor 4 and filling in the hole, be another section that duroplasts piece 3 and a hydraulic pressure capsule 2 of arc is bonded to an integral body again, fix an oil pipe on the hydraulic pressure capsule 2, become a monitoring device 10;
Monitoring device is serially connected by sensor signal cable rope 7 and pull rope 11 intervals 10-25cm, forms device string (as shown in Figure 3);
2, hole 12 from bottom to top at the underworkings of needs monitoring;
3, the anchor fluke 8 that will fix fixed pulley 9 is put on pull rope 11 usefulness drill steels and is headed at the bottom of the hole;
4, then by artificial pulling traction rope 11, will install string and hang in the hole, be drawn to the precalculated position;
5, by hydraulic oil pipe 6 to hydraulic pressure capsule 2 pressurization oil transportations to the 2MPa, make it that two duroplasts pieces 1 and 3 are strutted jam-packed in boring 12;
6, by signal cable rope 7 microseismic signals that receives is transferred to the main frame of data receiving center, carry out the microseism monitoring;
9, finish microseism monitoring after, open the pressure-relief valve of hydraulic tube, reclaim flat jack and reuse.
