How far should acrow prop be? This depends on the length of the work surface.
First of all, we need to understand the difference between "hydraulic support" and "single hydraulic prop"
1. The hydraulic support is an important part of the fully mechanized mining equipment. It can reliably and effectively support and control the roof of the working face, isolate the goaf, prevent the meteorite from entering the mining face and propelling the conveyor. It is used together with the shearer to realize comprehensive mechanization of coal mining, to solve the contradiction that the roof management in the mechanized coal mining work lags behind the coal mining work, further improve and improve the efficiency of coal mining and transportation equipment, and reduce the labor intensity of coal miners. Limit the safety of coal miners.
The hydraulic support is used on the fully mechanized mining face. The general width is 1.5m. According to the length of the face, it can be calculated how many hydraulic supports are needed. Of course, the selection of hydraulic supports has strict requirements and will not be described in detail here.
2. The single hydraulic acrow props use the liquid pressure to generate working resistance and realize the single retractable pillars for lifting and unloading. They are used on the working surface during general mining or blasting. Of course, the advanced support of the fully mechanized mining face is partially used in advance. Most of the brackets are supported by a single hydraulic acrow prop.
The spacing of the single hydraulic acrow props is divided into the column spacing and the row spacing. According to the length of the surface, it is possible to calculate how many monomers are needed, generally 60-100 cm.
In addition, the longest working face in China is currently more than 300m, and more than 200 of the fully mechanized support can be used on one side.
What kind of hydraulic acrow prop do you need? Tell me the length of your work surface, we will calculate exactly how many acrow props you need for you!!!
