Abstract
The invention discloses a coal sample collecting tank for a gas parameter measuring instrument, and belongs to the field of underground coal mine operation. The coal sample collecting tank comprises a tank cover and a tank body which are connected through threads, wherein locating pins are arranged at the top end in the tank body, a thermal insulation liner is further arranged in the tank body, locating grooves are formed in the outer part of the thermal insulation liner, and clamping grooves are formed in the tops of the locating grooves; and when the thermal insulation liner is located at the bottom of the tank body, the locating pins are clamped and connected to the clamping grooves, a gland is arranged at the top of the thermal insulation liner, and an air vent is formed in the top of the gland and connected with an air outlet nozzle through the tank cover. According to the coal sample collecting tank for the gas parameter measuring instrument, the thermal insulation liner is added on the basis of a conventional coal sample tank; a device which can isolate the thermal insulation liner and the tank body is provided, and influence of the tank body temperature on the liner is avoided; a seal ring is arranged outside the gland, the measurement accuracy is improved, and the structure is compact and reasonable; and the air outlet nozzle is a one-way air outlet device and can resist high pressure, and air tightness is guaranteed.
Description
Technical field
The present invention relates to a kind of borehole operation equipment, particularly relate to a kind of Gas explosion burns analyzer coal sample collection tank.
Background technology
Coal and gas prominent (hereinafter referred to as " giving prominence to ") is a kind of extremely complicated dynamic phenomenon occurring in underground coal mine, is the large disaster that downhole coal mine is produced.Outstanding along with strong coal body destruction, blowout of coal and gas; and form outburst hole and certain relief range; produce as pushed over mine car, destroying support, causing the dynamic effects such as air flow in laneway reverse; often can destroy underground equipment and ventilating system facility; and underground operators life is worked the mischief; sometimes also can there is gas explosion, expand hazard scope, cause great casualties and property loss.Therefore, Coal and Gas Outbursts Prediction work is that colliery normal safe produces requisite link, especially for coal and gas outburst mine and the mine with coal and gas prominent danger.Drilling cuttings desorption of mash gas index K1 and coal powder quantity of bore index S MAX prediction work face outburst hazard is utilized to be the outburst prediction technology be widely adopted, the prediction being mainly applicable to outburst danger within the scope of workplace in coal roadway tunneling, back production and stone door punching coal process and the measure effect inspection taking Anti-protrusion measure later, this method be workplace hand drill or electric rock drill to coal seam drilling, according in boring procedure every meter discharge coal powder quantity of bore number and discharge drilling cuttings desorption of mash gas index size prediction work in face of outburst hazard within the scope of drill with ferrule hole.Coal and gas prominent Parameters Instrument is for measuring Coal and Gas Outbursts Prediction forecast parameter, main measurement drilling cuttings desorption of mash gas index K1, overall target Kf (index be made up of the solid coefficient f value of K1 index and coal), supporting coal sample tank used on existing ore deposit, its structure is simple, in manually-operated process, hand contacts with coal sample tank, and hand temperature is namely comparatively large to the Influence on test result of Gas explosion burns instrument, has a strong impact on on-the-spot prediction work.
Summary of the invention
The object of the present invention is to provide a kind of Gas explosion burns analyzer coal sample collection tank, reasonable in design, overcome the deficiencies in the prior art, easy to maintenance, impermeability is good, and have good effect, the technical solution used in the present invention is:
