For the open-air blasting charging construction link, aiming at a low-water-level blast hole, the water depth is 0-1.5 m, if all water-resistant explosive is used in the hole, the charging cost is too high; if all the water-resistant explosive is used in the blast hole, the cost is low, but the explosive in the water-containing section at the bottom of the blast hole will fail, so that the root is caused.
Currently, woven bags, soil, bamboo, wood, air bags and other objects are used as partition objects for sectional charging, water-resistant and non-water-resistant explosive are separated, and an initiating explosive and a detonator are added in each section; these methods, while simple, do not achieve the desired effect: on one hand, the bottom of the blast hole is not provided with a hard support, the water-resistant explosive arranged at the bottom of the blast hole is approximately coupled with the explosive charge under the heavy pressure of the upper explosive column, and the water storage gap is not formed in the hole, so that the water level in the hole rises; on the other hand, if the open-air deep hole step is blasted, the charging condition at the bottom of the blast hole cannot be seen by naked eyes, and the bottom of the blast hole cannot be covered by a gun rod, so that the charging quality at the bottom of the sectional charging blast hole cannot be ensured.
In order to realize waterproof separation, reduce the using cost of the explosive and improve the blasting quality, the bottom of the low-water-level blast hole is provided with a cartridge-shaped water-resistant explosive, such as a second rock emulsion explosive; the upper part is provided with low-cost waterproof explosive such as porous ammonium nitrate fuel oil explosive; realizing sectional and bottom uncoupled continuous charging inside the blast hole; therefore, the simple charging separation device for the low-water-level blast hole is designed.
The invention comprises the following steps:
in view of the above, the invention designs a simple charging separator for the charging process of the low-water-level blast hole: the method not only gets rid of the high-cost water-resistant explosive used in the low-water-level blast hole, but also realizes the sectional and bottom uncoupled in-hole continuous charging construction in the blast hole; the cost of blasting explosive is reduced, and the blasting effect is improved.
The technical scheme provided by the invention is as follows:
a simple explosive separation device for open-air low water cannon hole segmentation loading, including being used for installing the separation dish of not water-resistant explosive and being used for binding the bracing piece of explosive cartridge shape water-resistant explosive, be provided with the dish seat in the bottom of separating the dish, vertical direction is provided with the mounting hole that is used for assembling the bracing piece in the dish seat, the internal diameter of mounting hole is greater than the bracing piece external diameter, transversely sets up the pin through-hole at the dish seat, be provided with the pin that is used for fixed dish seat and bracing piece in the pin through-hole, be provided with the through-hole that is used for installing the detonating cord in one side of separating the dish, be provided with the base of fixed stay bar in the bracing piece bottom.
As a further improvement, connecting ropes for lifting or placing the spacer are arranged at two ends of the pin.
As a further improvement, in order to be suitable for the big gun holes with different depths, the supporting rod is formed by connecting a plurality of supporting rod units in a threaded manner.
As a further improvement, the cross section of the support bar and the base is circular.
The separating disc is made of hard aluminum alloy material, and the supporting rod is made of iron material.
The invention has the beneficial effects that:
the structure is simple, the device is convenient and practical, and the cartridge-shaped water-resistant explosive, such as a second rock emulsion explosive, is filled at the bottom of the low-water-level blast hole; the upper part is provided with low-cost waterproof explosive such as porous ammonium nitrate fuel oil explosive; the construction embarrassment of using high-cost water-resistant explosive for all blastholes containing a small amount of water is eliminated, and the blasting charge cost is reduced.
