Description

The device for on-site processing and method of small-diameter explosive roll
Technical field
The invention belongs to engineering explosion technical field, the rock blasting available for fields such as mine, water conservancy and hydropower, traffic is applied In work, the device for on-site processing and method of specifically a kind of small-diameter explosive roll.
Background technology
In recent ten years, engineering explosion technology is developed rapidly, construction of water conservancy works, mine excavation, railway in China Important function has been played in the foundation of national economy construction such as (highway) build.To ensure that retaining rock is shaped and prevented by design profile face Only surrounding rock failure, it is necessary to which, using profile Controlled blasting technique, traditional outlining blasting is not coupled radially typically using axially spaced-apart Powder charge, and detonated with each powder stick of primacord series connection, to control the blast pressure in blasthole, realize the control to explosion damage effect System, but the use of the primacord of complete opening is through, cause blasting cost to increase, and process of binding limits speed of application, influences Project progress, in this case, underground borehole blasting outlining blasting technology obtain extensive concern, and its general principle is in profile Continuous charging is not coupled in periphery hole and air buffer is set, using explosion wave plug, air layer and powder charge area come Passback is passed, and extends acting duration of the surge on country rock, to obtain preferable demolition effect.Controlled with traditional profile Blasting technique is compared, and underground borehole blasting outlining blasting technology can obtain blast fragmentation size evenly, reduces unit powder consumption, is shown Write and save engineering cost, shorten the duration.In current tunnel blasting construction, a large amount of emulsion medicines for using 32mm and 35mm Volume, when carrying out tunnel outlining blasting, often using underground borehole blasting, to ensure preferable presplitting effect, diameter need to be used 25mm small diameter medicine roll, and in work progress, often lack the explosive of the specification.Therefore, worker is general in most of engineering Major diameter powder stick directly is twisted into small diameter medicine roll with hand to be used, or even presplitting is directly carried out using 32mm or 35mm powder sticks Explosion, coefficient of decoupling charge are unreasonable, it is easy to cause contoured surface to be destroyed, be unfavorable for the stabilization and engineering peace of engineering rock mass Entirely.
The content of the invention
The problem of inconvenient is obtained for current tunnel outlining blasting engineering medium-small diameter emulsion explosive cartridge, the present invention proposes A kind of easy small diameter medicine roll device for on-site processing and the processing method based on the device.The present invention the mechanism of action be, Because emulsion is in emulsion state, certain flowing can be produced when being acted on by external force, and have and necessarily maintain existing shape Ability, and the emulsion used in blasting engineering is packed using oilpaper or plastic film mostly, and packaging is with certain flexible change Shape ability, using this property, one end of large-diameter emulsified Explosive roll is cut, and be enclosed on incision with a plastic bag and overlap It is good, then explosive cartridge is extruded, on the premise of ensureing that the original packaging of explosive cartridge plays its protective capability, passes through a band hand The variable roll device of handle, diameter just can more easily obtain the small diameter medicine roll for meeting engine request.
