Abstract
The utility model relates to a hole sealing device in a coal mine, in particular to a drilling hole sealing device in a highly gassy mine, and solves the problem that the phenomena of drilling hole blockage and spraying as well as gas transfinite come out easily when a traditional drilling hole sealing device is used in highly gassy mine lots. The drilling hole sealing device in the highly gassy mine comprises a hole sealing pipe; the pipe orifice of the hole sealing pipe is connected with one end of a reducing-diameter three-way valve; another end and the third end of the reducing-diameter three-way valve are respectively connected with a water drainage box and two constant-diameter four-way valves which are connected in series through one of the two ends; the water drainage box and a gas-water separator are respectively connected to the rest two ends of the constant-diameter four-way valve in the middle; and a gas pipeline and a plug are respectively connected to the rest two ends of the constant-diameter four-way valve at the outer end. The utility model avoids the phenomena of drilling hole blockage and spraying, prevents gas from outgushing to cause gas transfinite, and well solves the gas-water separation problem at the same time, thereby ensure that no water is left in gas pipelines.
Description
Technical field
The utility model relates to the hole sealing device under the coal mine, is specially a kind of highly gassy mine drilling and sealing device.
Background technology
Existing research means shows, wanting to solve the gas problem can only be from the means of extraction, the negative pressure that so-called gas drainage under suction utilizes highly gassy mine drilling and sealing device (being plant equipment and dedicated line) to cause exactly, the gas that exists in the coal seam or discharge is released, be transported to the way in ground or other safe places, existing drilling and sealing device comprises the drill bit of Φ 108PVC hole sealing tube 1 and Φ 96, Φ 108PVC straight cross 2 is adopted in the aperture, carry out gas drainage under suction and gas-water separation, be specially at hole sealing tube 1 and install 4 cun straight cross 2 additional, straight cross 2 left sides directly are connected with hole sealing tube 1; Upside directly is connected with gas pipeline 3, and according to the gas situation in the boring, the size whether definite valve 4 that is connected with pipeline is opened and opened; Downside is connected with moisture trap in the process of drilling, and boring finishes the back and is connected with tailrace; Drill and be connected with the drilling rod fastening devices in the process in the right side, boring is installed 4 cun blind flanges 8 (as Fig. 1) additional after finishing.This kind connected mode is holed in the normal mine of gas amount and is retreated that gas enters hole sealing tube in the bar process, by moisture trap, tailrace water is separated with cinder, has improved the concentration of mash gas extraction; But in the mining area of high gas, normal construction process and move back in the bar process plug-hole, the spray orifice phenomenon that boring can occur, the gas of holing simultaneously control difficulty is big, causes the phenomenon of gas exceeding limit easily.
Summary of the invention
The utility model provides a kind of highly gassy mine drilling and sealing device in order to solve existing drilling and sealing device is prone to boring plug-hole, spray orifice phenomenon and gas exceeding limit phenomenon in the mining area of high gas problem.
The utility model is to adopt following technical scheme to realize: highly gassy mine drilling and sealing device, comprise hole sealing tube, the mouth of pipe of hole sealing tube is connected with an end of reducing tee, be connected with delivery box and two straight cross on the other end of reducing tee and the 3rd end respectively by arbitrary end series connection on it, remaining two ends are connected with delivery box and moisture trap respectively on the middle straight cross, and remaining two ends are connected with gaspipe line and plug respectively on the straight cross of outer end.During work, earlier jewel hole is carried out in the coal seam, the drilling rod that is connected with pump outlet constantly waters to drill bit, prevent the pre-heat affecting life-span of drill bit, when boring is finished when moving back the bar process, gas in the coal seam is because negative pressure can enter hole sealing tube, at this moment gas, cinder and water together enter hole sealing tube, because the diameter difference of drill bit and hole sealing tube is bigger, cinder can not be stuck between drill bit and the hole sealing tube, has avoided the boring plug-hole, the generation of spray orifice phenomenon is when gas amount is too high in the mine, by the negative pressure space cushioning effect of latter two straight cross, avoided the generation of gas exceeding limit phenomenon.
Hole sealing tube is a Φ 160PE hole sealing tube, not only can guarantee the gap between drill bit and the hole sealing tube during work, and is convenient to the installation of reducing tee, adopts 6 cun threeways that become 4 cun can realize connecting.
Increase straight cross between the straight cross of reducing tee and outer end, remaining two ends on the straight cross (two ends and straight cross and reducing tee are cascaded in addition) are connected with delivery box and moisture trap respectively, the space that when running into the extra high mine of gas, increases negative pressure by the increase straight cross, avoid the generation of gas exceeding limit phenomenon further, and ensure the concentration of gas in the gas pipeline better.
The utility model is by the expansion to the hole sealing tube diameter, at work progress and move back in the bar process, prevented the generation of boring plug-hole, spray orifice phenomenon, and in moving back the bar process, because the negative pressure space of hole sealing tube outer end is bigger, gas can not gushed out and cause the gas exceeding limit phenomenon, simultaneously by being connected with a plurality of delivery boxs, the fine problem that solves gas-water separation is guaranteed in the gas pipeline anhydrous.
