Description
Technical field
The present invention relates to field, colliery, particularly a kind of coal mine drilling endoscope spy on method.
Background technology
The work such as coal mining, roof control, roadway support are carried out in colliery, must grasp the geological conditions of roof as Roof rock feature, rock strength, different rock-layers thickness etc., to provide reliable foundation for the design of roof control, roadway support.
Inspection instrument for borehole is widely used in geological conditions assessment when coal production, roadway support design, mainly for detection of coal bed texture, geologic structure, roadway roof absciss layer (fragmentation), drilling quality, tunnel grouting effect, especially observe at the roadway roof absciss layer of bolting with wire mesh, the observation of face roof rock structure, intuitively, clearly can be shown by display.By recording digital code instrument, deposit work technician in a computer and analyze, make objective judgement and decision-making in time, the generation of accident can be avoided as far as possible, can be used as again the support form and parameter foundation that determine tunnel, reduce unnecessary input, video, image document can be preserved and do permanent record.Adopting inspection instrument for borehole to be the reliable method of one of detection roof strata geological conditions, is also carry out the basic element task of of roadway support at present.
Current inspection instrument for borehole device is ripe, and producer, the model of production are also many, but basic structure generally comprises 6 parts, comprises photoelectric probe, bracing or strutting arrangement, fastening devices, Flameproof box, display and or video recorder.Current small-bore, colliery inspection instrument for borehole can accomplish boring 360 degree of panorama wide viewing angle colours shooting around.
The inspection instrument for borehole probe diameter that colliery is commonly used is generally φ 22mm, bore diameter φ 28mm, drilling depth 10-20m, and internal battery can work 6 hours.
Because the rock strength of coal mine roof plate is generally smaller, and containing pore water, the rock stratum very poor to some roof conditions, often there is the problem such as roof fall, supporting difficulty, more need boring to spy on to this kind of coal mine roof plate and carry out observational study intuitively, thus provide technical support for roadway support and coal mine roof plate manage.
To the top board base program spied on of holing be, first upwards play the boring of 10-20m from top board with rig, bore diameter φ 28mm, then clean to bore flushing with water, then inspection instrument for borehole is opened, with support bar, inspection instrument for borehole is sent into boring, carry out in course of conveying recording or the rock stratum information at photo record different depth place, post-processed analysis.Because roof strata intensity is little, loose crushing, even if carried out punching cleaning before spying on, but when endoscope is to the conveying of boring deep, often have some fritter rock debris or mud drop probe on block eyeglass, thus cannot carry out spying on work, have to re-start operation, the work of spying on of such boring will carry out more than once repeated work, record also discontinuous, the power work limited time of equipment in addition, so be difficult to completing task on time, this considerably increases the labour intensity of staff, carrying out smoothly of work can not be ensured.
In sum; when adopting inspection instrument for borehole to detect; particularly during roof condition difference; the problem often run into be survey meter probe to boring conveying time; often there will be in top plate drilling have fritter rubble, clod drops and blocked by the eyeglass of probe; so that test job needs repetition, reduce operating efficiency.Therefore, the improvement and bring new ideas of the method for spying on of coal mine drilling endoscope is the problem needing solution at present badly.
Summary of the invention
For above-mentioned situation; for solving the defect of prior art; what the object of the present invention was just to provide a kind of coal mine drilling endoscope spies on method; effectively can solve prior art when detecting; often there will be in top plate drilling have fritter rubble, clod drops and blocked by the eyeglass of probe; so that test job needs repetition, reduce the problem of operating efficiency.
The technical scheme that the present invention solves utilizes the probe anti-fouler of coal mine drilling endoscope, then carries out according to the following steps:
1) according to the drilling design degree of depth and bore diameter rig from top board upwards drilling, drilling depth 0.5m darker in projected depth, then uses water that bore flushing is clean;
2) the probe anti-fouler of coal mine drilling endoscope is arranged on endoscope shell, fastening nut;
3) open inspection instrument for borehole and video tape recorder, with probe support bar, the endoscope probe of band probe anti-fouler is sent into boring, carry out recording, spying in course of conveying, the rock stratum information at record different depth place, for post-processed analysis.
The present invention is used for spying on perpendicular to the boring of top board, and method is simple, and result of use is good, the material such as rubble, clod can be blocked, and stop foreign matter to drop on probe eyeglass, substantially increasing operating efficiency, is the innovation spied in method of coal mine drilling endoscope.
