Technical Field

The utility model relates to a salvage device of solid matter under semi-closed minor diameter condition for when forging a powder (the explosive loads overfilling) among the mine blasting operation process, salvage out device with unnecessary partial explosive. The device can be widely applied to fishing porous granular ammonia oil explosives and emulsion explosives in mine blasting blastholes, and can also be widely applied to fishing other solids (granules, slurry and jelly) under the condition of semi-closed small diameter.

Background

In the process of blasting construction of a strip mine, the following reasons are often used: the failure metering of the explosive mixed loading truck is inaccurate, the explosive amount actually loaded in the blast hole exceeds the designed explosive amount due to misoperation of operators of the explosive mixed loading truck, blockage of the blast hole and the like, and if no measures are taken, the explosion energy generated by the explosive exceeding the designed explosive amount easily causes great safety accidents. Therefore, explosives exceeding the designed explosive amount need to be fished out of the borehole. At present, most mine blasting is medium-length hole blasting, and the depth of blast holes is 10-16 m. The prior method adopts a spoon-shaped device with a handle, and the handle end of the spoon-shaped device is fixed at one end of a bamboo pole and is used for salvaging explosives in a blast hole, but the method is slow in salvaging and low in efficiency. The bottom of the known fishing device is fixed or cannot be effectively controlled, and the material of the container is not specified.

Detailed Description

As shown in fig. 1 and 2, the device for fishing solid materials under the condition of semi-closed small diameter comprises a lifting rope 1, a handle 2 and a fishing barrel 3, wherein the lifting rope 1 is made of light, flexible and wear-resistant materials, and the tensile strength is greater than the weight of a fishing container filled with the fishing materials; the lifting rope 1 is tied in the middle of the handle 2; the handle 2 and the salvaging barrel 3 are connected in any way; the salvaging barrel 3 is arranged into a barrel shape with the thick upper part and the thin lower part, and the vertical distance between the barrel bottom and the edge of the barrel wall bottom is more than 5 mm; the barrel bottom is divided into a fixed part 4 and a movable part 5, the fixed part 4 is crescent, and the bottom area of the fixed part 4 is 10-20% of the area of the barrel bottom; the movable part 5 is movably connected with the barrel wall 7; the movable part 5 is intersected with the fixed part 4, and the area of the overlapped part is about 10% of the area of the barrel bottom; the movable part 5 is arranged at the upper part of the fixed part to prevent the salvaged explosive from leaking downwards; the fishing barrel 3 can be made of metal or plastic which does not generate sparks, and the density of the fishing barrel 3 is greater than that of fishing materials.

The length of the lifting rope 1 can meet the use requirement, and the measuring can be carried out, wherein the measuring starting scale starts from the handle position of the salvaging barrel; the maximum diameter of the salvaging barrel is less than or equal to (0.5-0.9) the diameter of a blast hole; the movable part 5 is movably connected with the barrel wall 7, a connecting pin is arranged, a spring is arranged at the connecting pin, and the movable part 5 is in an open state naturally; when the movable part 5 is in a natural state, the minimum included angle between the movable part 5 and the barrel wall is more than 20 degrees; when the salvaging barrel 3 sinks to salvage the explosive, the movable part 5 is opened, and when the explosive is filled and lifted upwards, the movable part 5 is closed downwards under the action of the gravity of the explosive in the salvaging barrel; a circle of gravity ring with the thickness of 1-5mm is arranged at the bottom of the wall of the fishing barrel so as to reduce the resistance of the fishing barrel during sinking.

Taking a blast hole with the diameter of 310mm as an example, the length of the lifting rope 1 is 10m, the upper part of the salvaging barrel 3 is designed to have the diameter of 250mm, the bottom diameter is 200mm, the barrel height is 500mm, and the density of the emulsion explosive is generally 1.05-1.25g/cm³If the weight of the salvaged explosive in each time of the salvaged barrel 3 is 21.12-25.14kg, the explosive column per meter needs to be salvaged for four times; when in use, the lifting rope 1 is tightened, and the head of the salvaging barrel is upwards put into the blast hole; because the mass density of the salvaging barrel material 3 is greater than the density of the explosive, the salvaging barrel 3 slowly and automatically sinks after contacting the surface of the explosive; after the explosive flows into the fishing barrel, the lifting rope 1 is pulled upwards, and under the action of the gravity of the explosive in the fishing barrel 3, the movable part 5 at the bottom of the fishing barrel 3 is automatically closed; and lifting the salvaging barrel 3 to the outside of the blast hole to pour out the explosive, and referring to the scales on the lifting rope 1 until the explosive in the blast hole reaches the designed explosive amount.
