Description
Technical field
The utility model belongs to the safety of coal mines prediction unit, particularly a kind of boring ickings temperature prediction bump device.
Background technology
Bump is one of typical dynamic disaster in coal mining and the geotechnics, directly threatening personnel's property safety of the production and the engineering construction in colliery, even can cause gas explosion and fire incident, causing producing and interrupt, damaging mine construction, is one of the most serious disaster in colliery therefore.At present, the coal in China exploitation is extended to the deep with annual about 10 meters speed, in following 10 years, China will have a great deal of mine to enter deep mining, and along with the increase of the degree of depth, the stress of coal body increases, coal body distortion and the elasticity potential that gathers are also big more, frequency and intensity that bump takes place will constantly increase, so bump advanced prediction and accurate to the prediction of deathtrap, and will be very important in time taking the regional precautionary measures and locality to separate right measure.Bump is under the high-ground stress condition in the digging process of coal seam, the off-load of hard fragility coal body excavation, cause coal seam stress to be concentrated, cause the elastic strain energy that is stored in the coal body to discharge suddenly, thereby the generation explosion gets loose, peels off, launches even a kind of colliery dynamic buckling disaster of throwing.In to the high-ground stress coal bed drilling process that bump danger is arranged, drill bit is subjected to resistance at the bottom of the hole and the pressure of hole wall will increase, therefore frictional force increases between drill bit and boring hole diapire and the sidewall coal body, and fraction time increases, thereby drill bit, hole diapire and ickings temperature all will rise.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, and providing a kind of can accurately judge, predict the coal mine work area danger of burst fast, reduces the boring ickings temperature prediction bump device of casualty loss.
The technical scheme that the utility model technical solution problem adopts is: boring ickings temperature prediction bump device comprises electric coal drill, twist drill rods, drill bit, be characterized in the output of electric coal drill, connecting rotary connector, outside the left side of rotary connector, place the dress conducting slip ring, be provided with the spline device between conducting slip ring and the electric coal drill right-hand member head, fixedly connected two sections twist drill rods that are provided with centre bore in the rotary connector right-hand member, the endoporus of the centre bore corresponding rotation connector of twist drill rods, radially being provided with wire guide in rotary connector communicates with the endoporus of rotary connector, conducting slip ring passes in the endoporus that wire guide extends rotary connector with lead one, together fixedly connected between two sections twist drill rods with drilling rod adapter sleeve screw thread, the fixedly connected drill bit of right-hand member head of twist drill rods, the centre bore inner armor thermocouple of drill bit, the left end peripheral equipment spring of thermocouple, right-hand member reaches bit exterior, below twist drill rods, establish two parallel rotatable fixed bars, fix a steel plate on a rotatable fixed bar therein, install two standing screws on the steel plate, the infrared thermometry probe is housed on another rotatable fixed bar, between conducting slip ring and infrared thermometry probe, connects data logger with lead two.
The beneficial effects of the utility model are: boring ickings temperature prediction bump device is easy to use, when the boring predicting rock burst, variations in temperature and aperture ickings temperature changing regularity at the bottom of the hole when measuring boring, the generation of prediction bump accident, a kind of new method is provided, and the on-the-spot instant playback of temperature data is judged the work plane shock hazard fast, also measurable colliery coal and gas are outstanding, and dynamic disasters such as other mines and tunnel rock burst.
