Abstract
The utility model belongs to mining construction technologies, and provides a charging device of an open-pit mine secondary punching field. The device adopts a flexible bag container (1); the lower end of the bag container (1) is filled with a massive weight (6); the lower end and the upper space of the bag container are closed; the bag container (1) are filled with two layers of explosives (7) and (8); detonating materials (4) are placed between the upper and the lower layers of explosives; and fillers (2) are arranged at the upper parts of the explosives. The device provided by the utility model avoids the loss of the explosives during the charging, saves the charging time, and further ensures the blasting quality.
Description
Technical field
The utility model belongs to the mining construction technology, mainly proposes a kind of opencut secondary punch district means for loading.
Background technology
Present many surface mines all be by original underground mining then carry out opencast, but because the lack of standard adopted originally, cause the goaf of each step bottom now many and complicated.The method of normal now employing avalanche is handled, and allows the step slump tamp the goaf, bottom, and we claim this part to handle the zone of being tamped after the slump of dead zone is the secondary punch zone.Because the zone that is filled with can not be tamped fully, so all to be us generally speaking said in the hole in secondary punch zone stone riprap cinder hole.This hole has two kinds, and a kind of is that the middle part, hole has big slit or little insteady and sure district; Another kind is that big slit or little insteady and sure district are arranged at the bottom, hole.Random hole powder charge is a troubling problem always, because the explosive of surface mine mainly contains ammonium nitrate-fuel oil mixture and emulsion now, the slit in random hole and little insteady and sure district can allow a large amount of explosives run off, and have had a strong impact on the quality of explosion.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of opencut secondary punch district means for loading, to solve the problem that the explosive that exists in the powder charge process of random hole runs off, influences blasting quality.
The utility model is finished the technical pattern that its invention task taked: adopt gentle type bag-like container, be filled with block weight in the lower end of bag-like container, and with the lower end of bag-like container and upper space sealing, the two-layer explosive of filling in bag-like container, and placing detonating material between the two-layer explosive up and down, the top of explosive is charges.
The specific operation process of the utility model means for loading is:
The utility model device is mainly used in deep hole, as required powder charge position is 710 meters dark random cinder holes, there is a little insteady and sure district at its middle part, the bottom has the powder charge in the secondary punch zone of part stone riprap, the flexible bag-like container length of design〉15 meters, insert block weight in the bottom of bag-like container, tie this end, bag-like container is put down along the hole, and bag can not be reversed, put to the bottom at bag, in bag, pour explosive into, install end medicine, in bag, insert detonating material, pour the top explosive then into, carry out filling after powder charge finishes.
Device of the present utility model can make that explosive can not run off in the powder charge process, can save the time of powder charge and the quality of explosion also is guaranteed simultaneously.
Description of drawings
Fig. 1 is the utility model user mode schematic diagram.
Among the figure, 1, bag-like container, 2, charges, 3, little steady and sure district, 4, detonating material, 5, stone riprap, 6, block weight, 7, the bottom explosive, 8, the top explosive.
The specific embodiment
In conjunction with the accompanying drawings the utility model embodiment is illustrated:
As shown in Figure 1, the utility model device main body is a length greater than 10 meters flexible bag-like container 1, the lower end of its container have block weight 6 and will insert the lower end of weight and top between seal, have two-layer explosive 7,8 in its bag-like container and detonating material 4 is set between two-layer explosive, the superiors are charges 2, and the blastic fuse of detonating material causes container upper end and detonates in order to control.
Claims (1)
1, a kind of opencut secondary punch district means for loading, it is characterized in that: adopt flexible bag-like container (1), be filled with block weight (6) in the lower end of bag-like container (1), and with the lower end of bag-like container and upper space sealing, the two-layer explosive of filling (7) (8) in bag-like container (1), and placing detonating material (4) between the two-layer explosive up and down, the top of explosive is charges (2).
