Abstract
Disclosed are a device and a method for sealing and drilling holes of gas drainage. The device comprises a barrel with a plurality of holes, a layer of an inner film is attached to the inner wall of the barrel, a barrel front cover and a barrel back cover which are sleeved on a barrel drainage pipe are respectively arranged on two sides of the barrel, an annular ring board is positioned in the barrel, a spring is mounted on one side of the annular ring board, a plurality of pricking pins and pull lines are mounted on the other side of the annular ring board, and a polyurethane isocyanate bag and a polyurethane combined polyether bag which are sleeved together are arranged in the barrel. When the device is sent to the needed position in a drilling hole with the gas drainage pipe, the pulling line is pulled so that the pricking pins on the annular ring board prick the polyurethane isocyanate bag and the polyurethane combined polyether bag, two slurries in the bags flow out for mixing, the annular ring board is repeatedly pulled for multiple times, slurries in the polyurethane isocyanate bag and the polyurethane combined polyether bag are repeatedly stirred and fully mixed, sealing materials which are obtained by the reaction of the mixed slurries continuously swell until the inner film bursts, the sealing materials are extruded from the plurality of holes on the wall of the barrel and are closely attached to the drilling holes, and the sealing of the drilling holes is achieved.
Description
Technical field
The present invention relates to a kind of drilling and sealing method, belong to coal mine lower area gas control technology and equipment field, especially relate to the coal mine down-hole drilling hole sealing technology.
Background technology
Gas accident is major casualty under the coal mine, and national control of coalmine gas policy confirms that highly gassy mine must be taken out afterwards earlier and adopt that gas pumping is the measure of effecting a permanent cure.China's coal-mine gas pumping rate is generally lower; Except the influence of geological conditionss such as gas permeability of coal seam difference, most important reason is that the sealing quality of boring is poor, effectively crack around the shutoff boring; It is fast to cause the colliery gas density decay in the extraction process, to occur, and gas flow is low.
China's coal-mine is generally used organic resin material or other macromolecular material at present, and these materials generally carry out hybrid reaction by two or more chemical grout and generate.Conventional method is to mix the number of chemical slurries through manual, utilizes cotton to adsorb after the stirring and is wrapped on the gas pumping pipeline, inserts the extraction hole in the lump with the gas pumping pipeline; Since from chemical grout from beginning to be mixed into the only tens seconds blanking time (usually less than 30s) of foaming; Thereby usually the gas pumping pipe in the extraction hole in the progradation mixed serum begun foaming and intumescing, stop further to advance, can't send to the sealing of hole position of setting; Do not reach the sealed borehole length of design; General 3 ~ the 4m of sealed borehole length, the sealing of hole section can not form effective seal in boring cranny development position.The several workmans of this arts demand are skilled in technique and close fit in addition, and workman's skin contacts chemical grout easily, and human body is had certain harm.
Summary of the invention

Technical scheme: mash gas pumping drilling hole sealing device of the present invention; Comprise the cylinder that is furnished with some holes; Be attached with one deck inner membrance on the cylinder inner wall, the both sides of cylinder are respectively equipped with cylinder protecgulum and the cylinder bonnet that is sleeved on the gas pumping pipe, are provided with the Circular Plate that is furnished with a plurality of holes on the end face in the cylinder; Circular Plate one side is arranged with the spring that links to each other with the cylinder protecgulum; Be furnished with some prickers on the opposite side end face of Circular Plate, and be arranged with two stay cords that stretch out cylindrical outer, be provided with the black material of polyurethane capsule bag that is fixed on the gas pumping pipe and the polyurethane that is sleeved on the black material of the polyurethane capsule bag between Circular Plate and the cylinder bonnet and expect the capsule bag in vain.
The length of described cylinder is 0.2 ~ 0.5m, and diameter is 100mm.
Mash gas pumping drilling method for sealing of the present invention may further comprise the steps:
After the cylinder protecgulum that a. will link to each other with the Circular Plate spring is fixed with the cylinder that is furnished with some holes one end that adheres to one deck inner membrance; Be sleeved on the gas pumping pipe; Then nestable polyurethane together black material capsule bag and polyurethane are expected that in vain the capsule bag for packing fruits on is on the gas pumping pipe; Send in the cylinder, the cylinder bonnet is packed into is fixed on the other end of cylinder afterwards;
B. the gas pumping pipe is inserted in the mash gas pumping drilling; Apart from aperture 0.5～1 m, outwards pulling is fixed on the stay cord on the Circular Plate, and the pricker on the Circular Plate punctures polyurethane black material capsule bag and polyurethane is expected the capsule bag in vain; Two kinds of slurries outflows in the bag are mixed; Mixed serum to cylinder protecgulum direction, spurs Circular Plate repeatedly through a plurality of orifice flows on the Circular Plate repeatedly, makes the black material of polyurethane capsule bag and polyurethane expect in vain that slurries in the capsule bag stir fully repeatedly and mixes;
C. the encapsulant that mixed slurry reaction generates constantly expands, and bursts inner membrance, and extrudes the some holes from the cylinder barrel and the hole wall of holing is combined closely, and realizes the sealing to boring.
Beneficial effect: owing to adopted technique scheme, utilize the cylinder that polyurethane black and white material capsule bag is housed, can realize the regulation and control of sealing of hole position; Can satisfy the requirement of design sealed borehole length, and a firm reaction compartment is arranged, through puncturing black and white material capsule bag; Make the slurries hybrid reaction in the black and white material capsule bag generate new encapsulant; Encapsulant constantly expands, and bursts the hole wall of extruding inner membrance and the some holes from the cylinder barrel and holing and combines closely, and realizes the sealing to boring.Have characteristics simple in structure, easy to operate, that controllability is strong, harmless.
