Description
Technical field
The invention belongs to the blast hole projectile filling blasting technique field of bargh, relate in particular to a kind of easy settling borehole explosion combined spacer.
Background technology
At exploitated ore or when exploiting other solids, usually on by the exploitation thing, bore a deep hole with rig or miscellaneous equipment, then filling explosive in this hole carries out explosion, and thing is quick-fried to fall so that exploited, and then reach the purpose of exploitation, but directly toward the interior filling explosive of deep hole, the Energy distribution that sometimes its explosion produces is inhomogeneous, not only causes the unit consumption dose large, and boulder yield is high, affects blasting quality.
The blasting hole spacer be a kind of in blasting hole interval a kind of device of material of the same race not, its effect is that explosive energy is evenly distributed, and is mainly used in the big gun hole of mining explosion.During use, spacer can be placed on the design attitude in the blast hole, then carries out the operation such as filling explosive, filling, line of blasting hole on spacer, and carrying out explosion after complete detonates.Use spacer that explosive energy is fully utilized, save explosive, improve blasting quality, reduce the exploitation blasting cost, also can offer help for special explosion design simultaneously.Chinese patent ZL02276267.1 discloses a kind of blasthole gas spacer, it is to consist of this class spacer by the airbag of flexibility and the aerating device in the airbag, utilize the Compressed Gas filling airbag that discharges the gas cylinder in the airbag, the gas filling airbag that perhaps utilizes gas generator to produce, make airbag and explosion hole wall close contact after the inflation, form bearing capacity, realize the interval filling of explosive in the blast hole, but the Compressed Gas of this spacer exists potential safety hazard in transportation is carried, and structure is loaded down with trivial details, troublesome poeration, inefficiency, the size of isolation is inaccuracy also, thereby affects quality and the effect of explosion.
Chinese patent ZL200620161101.8 discloses a kind of gas spacer, does not need high-pressure gas, but adopts compressor directly to inflate, but prerequisite is must be equipped with a kind of special-purpose charger in use, cost is higher, and simultaneously complicated during operating cost, efficient is low.All there is the problem of cracky when running into sharp object in the airbag of above-mentioned two kinds of spacers.
Chinese patent ZL01212086.3 deep hole balst spacer, to be consisted of by two dividing plates and the pillar that is located between this two dividing plate, though simple in structure, but dividing plate is rigid solid, enter in the blast hole and can not tightly coincide with the blast hole shape, size hour, the sealing in upper lower clapboard space is poor, affects demolition effect.When size is large, with the easy clamping stagnation of hole wall, cause to arrive desired location, bursting work can not be carried out smoothly.
