Description
Technical field
The utility model relates to blasting technique, particularly relates to a kind of deep hole demolition uploading pressure device.
Background technology
Deephole bench blasting is one of the topmost erosion control release in present colliery means, concentrates solution danger to have vital effect to stress in coal bed.Conventional unloading pressure by blasting device takes to bring out explosion, and its explosive payload is more, and operation is comparatively complicated, after explosion, coal deformation is comparatively serious, and cause coal supporting to lose efficacy, roadway deformation is large, and construction drill is more, be unfavorable for producing, in deep hole blasting device of the prior art, because majority adopts the plastic tube of integrally closed, inconvenient when loading fried explosive cartridge and detonator, and when filling the material such as clay stemming or water stemming material, be not easy to grasp the length of filling, bring certain difficulty to constructing operation.
Utility model content
The purpose of this utility model is, overcomes the weak point of existing blasting technique, provides a kind of deep hole demolition uploading pressure device, not only possess the function of unloading pressure by blasting, and convenient filling, can the length of accurate perception packing material, alleviate work difficulty, be conducive to the carrying out of production work.
A kind of deep hole demolition uploading pressure device described in the utility model, includes PVC plastic pipe, film, explosive cartridge, detonator, clay stemming, water stemming material, snap device, detonator payment to a porter and transparent plastic scale.PVC plastic pipe is the main component of a kind of deep hole demolition uploading pressure device described in the utility model, described pvc pipe is divided into upper and lower two semicanals, upper and lower two semicanals are by being connected with the middle snap device arranged at pvc pipe two ends, the inside, one end that described each semicanal stretches into boring is provided with powder charge district, be provided with film in described powder charge district and powder charge is distinguished into equal compartment, explosive cartridge and detonator is placed with in described compartment, described detonator outer end is provided with detonator payment to a porter, detonator is connected in parallel, outside detonator payment to a porter connecting line, packaging has waterproof insulation adhesive plaster, and 200mm aperture is extended in PVC plastic pipe, described powder charge section length is less than 1/2nd of PVC plastic length of tube.Rear, powder charge district is provided with clay stemming, be used for shutoff powder charge district, the shutoff length of described powder charge district rear clay stemming is 40 ~ 50mm, and clay stemming rear is provided with water stemming material, and the number of described water stemming material is 2, also clay stemming is provided with at water stemming material rear, at rear, powder charge district, the peripheral side of PVC plastic pipe, is provided with strip opening, being provided with the transparent plastic scale coincide with opening shape at opening part, being used for grasping the length of loading when loading stemming.When operation, first lower tube half is placed in plane, in powder charge district, explosive volume and detonator, by outside detonator payment to a porter fairlead, load onto upper tube half, then clay stemming is filled, controlled the length of filling by transparent plastic scale, and then fill water stemming material, finally recharge clay stemming, then PVC plastic pipe is placed in boring, ignites.
A kind of deep hole demolition uploading pressure device described in the utility model, overall structure is simple, easy for operation, good stability, reliability is high, use a kind of deep hole demolition uploading pressure device described in the utility model, not only possess the function of unloading pressure by blasting, and convenient filling, can the length of accurate perception packing material, alleviate work difficulty, be conducive to the carrying out of production work.
