Abstract
The utility model discloses a kind of coal seam rapid hole sealing pressure measurement structure, comprise the boring be in tilted layout, drilling axis direction is arranged a sealing of hole sleeve pipe, between boring lower end and sealing of hole sleeve pipe tube wall, polyurethane seal plug is set, polyurethane seal plug bottom arranges a Grouting Pipe, Grouting Pipe upper end open extends above described plug, polyurethane seal plug top arranges a slurry recovering tube, slurry recovering tube upper end is near sealing of hole sleeve upper end, slurry recovering tube parallels with sealing of hole sleeve pipe and Grouting Pipe three, cement paste is filled with between boring and sealing of hole sleeve pipe, sealing of hole its lower end sets gradually valve, malleation table and airduct, airduct injects blast by valve in sealing of hole sleeve pipe.The utility model can realize the quick pressure measurement operation in coal seam, reduces the work plane pressure measurement time, guarantees to produce and normally carries out in order.
Description
Technical field
The utility model belongs to mine quick pressure measurement drilling and sealing construction technology, relates to a kind of coal seam rapid hole sealing pressure measurement structure.
Background technology
Colliery adopts conventional pressure testing method to coal bed pressure measurement work always, and the pressure testing method that the method mainly adopts coal-bed gas pressure slowly to go up carries out.Determination of coal seam gas pressure works, and the time that this pressure testing method needs is longer, and piezo-effect is not obvious, arranges special messenger's pressure measurement time long, the 15 day time of minimum needs; In order to change the status quo, implement quick pressure measurement, reduce the work plane pressure measurement time, improve the tunnelling time, create good safety production condition for shaft production continues, spy carries out project improvement to determination of coal seam gas pressure.
Summary of the invention
The purpose of this utility model is to provide a kind of coal seam rapid hole sealing pressure measurement structure, can realize the quick pressure measurement operation in coal seam, reduces the work plane pressure measurement time, guarantees to produce and normally carries out in order.
The purpose of this utility model realizes like this, a kind of coal seam rapid hole sealing pressure measurement structure, comprise the boring be in tilted layout, drilling axis direction is arranged a sealing of hole sleeve pipe, between boring lower end and sealing of hole sleeve pipe tube wall, polyurethane seal plug is set, polyurethane seal plug bottom arranges a Grouting Pipe, Grouting Pipe upper end open extends above described plug, polyurethane seal plug top arranges a slurry recovering tube, slurry recovering tube upper end is near sealing of hole sleeve upper end, slurry recovering tube parallels with sealing of hole sleeve pipe and Grouting Pipe three, cement paste is filled with between boring and sealing of hole sleeve pipe, sealing of hole its lower end sets gradually valve, malleation table and airduct, airduct injects blast by valve in sealing of hole sleeve pipe.
The utility model structure artificially injects blast by sealing boring, the blast of artificial injection is that the manometric numerical value of pressure measuring drill hole reaches certain pressure instantaneously, drop to after a steady state value until this manometric numerical value, re-inject blast, the numerical value reached instantaneously carries out the contrast of the twice manometric steady state value in front and back after recovering, if differ less, then the pressure measurement of this boring reaches steady state value, stopping blast after pressure stabilisation, carry out determination of coal seam gas pressure state, achieve pressure measurement fast and efficiently.The utility model structure can reduce the work plane pressure measurement time greatly, and the pressure measurement time was reduced by least 5 days more in the past, can realize the quick pressure measurement operation in coal seam, guarantees to produce and normally carries out in order.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is main TV structure schematic diagram of the present utility model.
Detailed description of the invention
A kind of coal seam rapid hole sealing pressure measurement structure, as shown in Figure 1, comprise the boring be in tilted layout 8, hole on 8 axis directions and a sealing of hole sleeve pipe 3 is set, hole between 8 lower ends and sealing of hole sleeve pipe 3 tube wall and polyurethane seal plug 6 is set, polyurethane seal plug 6 bottom arranges a Grouting Pipe 5, Grouting Pipe 5 upper end open extends above described plug 6, polyurethane seal plug 6 top arranges a slurry recovering tube 4, slurry recovering tube 4 upper end is near sealing of hole sleeve pipe 3 upper end, slurry recovering tube 4 parallels with sealing of hole sleeve pipe 3 and Grouting Pipe 5 three, cement paste 7 is filled with between boring 8 and sealing of hole sleeve pipe 3, sealing of hole sleeve pipe 3 lower end sets gradually valve, malleation table 2 and airduct 1, airduct 1 injects blast by valve in sealing of hole sleeve pipe 3.
