Abstract
A kind of ascending hole coal seam gas pressure measurement water pressure excluding instrument and method are particularly useful for occurring the test of hydraulic pressure situation in ascending hole coal seam gas piezometry process.It is connected the pressure meter on the piezometer tube by the piezometer tube that inserts in the boring, and the water collect tank that connects through triplate line constitutes.Method comprises construction drill, and piezometer tube is inserted in the boring, by injection hole sealing, with threeway piezometer tube, pressure meter and water collect tank is connected as one.Water in the determination of coal seam gas pressure process in the boring flows in the water collect tank by piezometer tube under the deadweight effect, discharge by the II valve at water collect tank lower part outlet place again, play the effect of rejecting hydraulic pressure, methane gas is overflowed, improved the accuracy of determination of coal seam gas pressure greatly, it is simple to operate, and cost is lower.
Description
Technical field
The present invention is ascending hole coal seam gas pressure measurement water pressure excluding instrument and method, relates to the method for determination of coal seam gas pressure, is particularly useful for occurring in ascending hole coal seam gas piezometry process the situation of hydraulic pressure.
Background technology
The most collieries of China are high gas or projecting mine, and gas accident is " bottleneck " factor of restriction Safety of Coal Mine Production, accurately measures coal-bed gas pressure and has very important significance for Safety of Coal Mine Production.Aspect determination of coal seam gas pressure, carried out multiple research both at home and abroad, and proposed different pressure testing methods, as yellow mud-cement manometric method, cushion rubber (capsule) hole packer manometric method, cushion rubber (capsule)-pressure mucus manometric method, slip casting manometric method etc.But, owing in the determination of coal seam gas pressure process, run into the situation that hydraulic pressure occurs, cause determination of coal seam gas pressure inaccurate through regular meeting, this problem is never effectively solved a difficult problem that becomes determination of coal seam gas pressure.
Summary of the invention
Technical problem: the purpose of this invention is to provide a kind of simple in structurely, easy to operate, measure ascending hole coal seam gas pressure measurement water pressure excluding instrument accurately.
Technical scheme: the present invention is an ascending hole coal seam gas pressure measurement water pressure excluding instrument, comprise the piezometer tube that inserts in the boring, be connected the pressure meter on the piezometer tube, on described piezometer tube and union that pressure meter is connected, be provided with threeway, connect a water collect tank through triplate line, water collect tank upper entrance place is provided with the I valve, and water collect tank lower part outlet place is provided with the II valve.
Ascending hole coal seam gas pressure measurement water pressure excluding method of the present invention: comprise construction drill, piezometer tube is inserted in the boring,, be connected the water collect tank that a position is lower than the pressure meter position all the time with pressure meter pipeline junction with threeway at piezometer tube by injection hole sealing.In the determination of coal seam gas pressure process, the water in the boring flows in the water collect tank by piezometer tube under the deadweight effect, discharges by the II valve at water collect tank lower part outlet place again, plays the effect of rejecting hydraulic pressure.
Beneficial effect: the present invention is owing to be provided with water collect tank, and when hydraulic pressure occurring in the boring in the process of determination of coal seam gas pressure, water flows under the deadweight effect in the water collect tank, discharges by the II valve at water collect tank lower part outlet place again, plays the rejecting hydraulic action.Can emit the hydraulic pressure that exists in the pressure measurement process by water collect tank methane gas is overflowed, improve the accuracy of determination of coal seam gas pressure greatly, provide reliable guarantee for accurately measuring coal-bed gas pressure.It is simple to operate, and cost is lower, has practicality widely in the present technique field.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: the 1-piezometer tube; The 2-threeway; The 3-pressure meter; The 4-I valve; The 5-water collect tank; The 6-II valve.
The specific embodiment
The invention will be further described below in conjunction with the embodiment in the accompanying drawing:
Ascending hole coal seam gas pressure measurement water pressure excluding instrument of the present invention, mainly by the piezometer tube 1 in the boring, pressure meter 3 and water collect tank 5 constitute, the union place that piezometer tube 1 is connected with pressure meter 3 is equipped with threeway 2, through threeway 2 piezometer tube 1, pressure meter 3 and water collect tank 5 are connected as one, the I valve 4 of control channel switch is equipped with at water collect tank 5 upper entrance places, and the II valve 6 of gauge tap is equipped with at water collect tank 5 lower part outlet places.
Ascending hole coal seam gas pressure measurement water pressure excluding method of the present invention: construction drill at first, then piezometer tube 1 is inserted in the boring, be mounted to predetermined hole sealing depth, and install Grouting Pipe, after sealing with polyurethane or timber wedge etc., the aperture begins slip casting, then connect piezometer tube 1, pressure meter 3 respectively with threeway 2 with water collect tank 5, the position of water collect tank 5 is lower than the position of pressure meter 3 all the time.When hydraulic pressure occurs in the boring in the determination of coal seam gas pressure process, water flows in the water collect tank 5 by piezometer tube 1 under the deadweight effect, discharges by the II valve at water collect tank lower part outlet place again, plays the effect of rejecting hydraulic pressure.When using at the scene, arrange special watt inspection person regularly to discharge water; When discharging water,, at first close I valve 4, then open II valve 6 in order to prevent the methane gas effusion; After treating that water collect tank 5 interior current finish, at first close II valve 6, then open I valve 4; Can repeatedly repeat to discharge water, close II valve 6 immediately when the port of export of discovery water collect tank 5 has bubble to overflow and open I valve 4, discharging water finishes.
