Description

Technical Field

[0001] The utility model belongs to the technical field of underground mine processing and relates to a drainage and wind blocking device suitable for an underground vein chute system of a mine. Background Art

[0002] In the mine, the ventilation system of the mine and the control effect of flooding have a great impact on production safety. The existing technology uses the development project (branch joint) as the air intake system and the mining project (filling return air duct) as the return air system. At the same time, due to practical needs, the chute mine in the vein needs to be retained in the form of a branch well box during the mining process. When the depth of the original chute mine exceeds a middle section (60 meters), the following will occur: ① This well will absorb the fresh air flow entering the mine, resulting in insufficient ventilation of the mine; ② It will absorb the polluted air with hot water vapor in the mine. When the two different airflows meet here, water flow will be formed; ③ The downward filling mining method is adopted, so that the filling water around the original chute mine retained in the form of a branch well box will continue to seep out. This situation not only leads to the disorder of the mine ventilation system, but also increases the moisture content of the ore, which is easy to cause the chute mine to be blocked, resulting in production organization disorder. Therefore, this problem needs to be solved urgently. Utility Model Content

[0003] The purpose of the utility model is to address the problems existing in the prior art and to provide a drainage and wind-blocking device suitable for an underground vein chute system in a mine, which solves the problem of dispersion and loss of fresh airflow in the mine working area and the problem of different airflows, such as the water flow generated by the intersection of fresh airflow and hot water steam polluted air, and the filling seepage water entering the chute and causing blockage of the chute.

[0015] The technical solution of the utility model is described below in conjunction with the accompanying drawings and implementation methods.

[0016] like Figure 1 As shown, a drainage and wind-blocking device suitable for an underground vein chute system in a mine comprises two symmetrically arranged frames 1, wherein the frames 1 adopt a triangular prism structure, and the purpose of the arrangement is that the bottom of the triangular prism can play a good stabilizing role; wherein an edge 6 is provided on the top of any one of the frames 1, and the length of the edge 6 is 5-10 cm, which just fits on the top of the frame 1 on the opposite side, so that the two frames 1 are buckled and connected by the edge 6, which is convenient for collecting water flow and blocking the rising of wind flow.

[0017] The two assembled frames 1 are provided with a veneer body 2 on the outside and a square groove 3 on the bottom edge, which is formed by connecting four independent U-shaped channel steels to form a square. In addition, the groove 3 is provided with a liquid outlet 4, and a drainage pipe 5 is provided at the bottom of the liquid outlet 4, and the two are connected to collect water flow to achieve the effect of centralized drainage.

[0018] Specifically, the material of the present invention is stainless steel.

[0019] The utility model is used in the following process:

[0020] During the process of switching to the middle section of the mine, the size of the chute is reduced by changing the size of the support shaft box during the filling process of the penultimate layer of the mine to keep it consistent with the scale of the device to ensure tightness and fit after installation; after the first layer of the next middle section is opened, the position of the chute is found through the middle section tunnel and the utility model is installed.

[0021] When in use, the utility model not only prevents the fresh air flow from being drawn upward, thus solving the problem of fresh air flow diversion in the mining area, but also prevents the polluted air from descending, thus solving the water flow problem caused by the encounter between the polluted air and the fresh air flow; at the same time, it solves the problem of centralized collection and drainage of the filling water around the original chute mine after continuous seepage, plays the role of "drainage and wind blocking", and solves the problems of blockage of the chute mine in the vein and poor ventilation in the mining area.
