Abstract
The invention provides an isolation installation method for open-pit mine deep-hole blasting rock and explosive. The explosive is firstly arranged at the bottom part of a blast hole, an isolation plug with the diameter which is applicable to the diameter of the blast hole is suspended at the place which has a distance of 1 meter to the liquid level of the explosive through a suspension rope and a support rod which is supported at the blast hole mouth, and rock powder is filled on the isolation plug. The isolation installation method has the advantages of simple process, good blasting effect and high utilization ratio of the explosive.
Description
Technical field:
The present invention relates to a kind of explosive installation method, relate in particular to a kind of explosive installation method that is used for the opencut deep hole blasting
Background technology:
The explosive installation method that uses is the bottom that explosive is installed in the big gun hole at present, be placed with rock dust more in the above, because rock dust is a bulk solids, its density is greater than the density of emulsion, and emulsion is the viscoloid that flows, and when rock dust falls to the explosive liquid level from the aperture, easily causes rock dust to mix with explosive, cause the part explosive to lose efficacy, the capacity usage ratio of explosive is not high
Summary of the invention:
Purpose of the present invention just provides a kind of opencut deep hole blasting rock connective from installation method, this method can make rock dust and explosive fully isolate, and has avoided mixing of rock dust and explosive, can improve the utilization rate of explosive energy.
Installation method of the present invention is as follows:
(1) earlier explosive is put into bottom, big gun hole;
(2) batching pig that again a diameter and big gun bore open is adapted is suspended in from 1 meter high place of explosive liquid level by suspension rope and the frame support bar at bubble mouthful, and described batching pig is cylindric, hollow, make by abrasive rubber, easily sink to, can in batching pig, put into stone in order to make batching pig;
(3) on batching pig, fill rock dust
Technology of the present invention is simple, and demolition effect is good, explosive utilization rate height
Description of drawings: the mounted explosive schematic diagram of Fig. 1 the inventive method
The specific embodiment:
Contrast Fig. 1 as can be known: installation method of the present invention is the bottom that earlier explosive 1 is placed in the big gun hole, the batching pig 2 that a diameter and big gun bore open are adapted is suspended in from 1 meter high place of explosive 1 liquid level at the support bar 3 of gun muzzle by suspension rope 4 and frame again, described batching pig 2 is cylindric, hollow, make by elastomeric material, described rock dust 5 be placed on batching pig 2 above.
Claims (2)
1. an opencut deep hole blasting rock, connective are from installation method, and its feature is as follows:
(1) earlier explosive is put into bottom, big gun hole;
(2) batching pig that again a diameter and big gun bore open is adapted is suspended in from 1 meter high place of explosive liquid level by suspension rope and the frame support bar at bubble mouthful;
(3) on batching pig, fill rock dust.
2. method according to claim 1 is characterized in that described batching pig is cylindric, and hollow is made by abrasive rubber.
