Open pit mine larger water sprinkler high efficiency water adding method

Abstract

An open pit mine larger water sprinkler high efficiency water adding method is disclosed. The invention relates to the open pit mine large water sprinkler high efficiency water adding method. The method comprises the steps of planning a water adding site, determining the construction location of a high water pool, determining the height different between the bottom water outlet of the high level water pool and the water sprinkler water adding site, determining the diameters of conveying water pipes from a water source point to the high water pool and the water adding site, and determining the water pumping speed of a water source site water pump. The thickening of the conveying water pipe diameter in a full distance is not needed, thus the water flow of a large diameter water outlet can satisfy the need of filling water in a shortest time, and the above proposed problem can be solved.

Description

technical field [0001] The invention belongs to the technical field of mining machinery and relates to a water adding process, in particular to an efficient water adding method for a large sprinkler used in open-pit mines. Background technique [0002] Large-scale open-pit mines are seriously dusty, especially in stopes that use automobile transportation technology. The dust generated during the passing of production vehicles is very harmful to on-site equipment and operators. In order to meet the requirements of environmental protection, post hygiene, and equipment maintenance, mines need Sprinkle water continuously with sprinkler to reduce dust. [0003] Due to the wide working area of ​​the stope, the sprinkler needs to run efficiently to meet the requirements of dust prevention and environmental protection. The working process of the sprinkler is divided into two stages: adding water and sprinkling water. The measure to improve the working efficiency of the sprinkler is...

Problems solved by technology

[0004] Traditional way of adding water (such as image 3 ): From the water source point 11 to the water filling point 10, a small-diameter water delivery pipe 1 is erected. The advantage of this scheme is to save investment costs and power costs. The disadvantage is that the small-diameter water delivery pipe 1 is too small. Insufficient, the sprinkler takes a long time to add water and the work efficiency is low;

[0005] The traditional way of adding water (such as Figure 4 ): From the water source point 11 to the water filling point 10, a large-diameter water delivery pipe 4 is erected to meet the needs of the sprinkler. The advantages of this scheme are that the water flow per unit time at the water outlet is relatively large, the time for adding water is short, and the sprinkler has a high working efficiency. The disadvantages are Investment cost and use cost are doubled compared with the former

[0006] The above two water adding methods cannot achieve the optimal effect of short water adding time and low water adding cost, and cannot be widely used in production
