The initial support force refers to the active support force provided by the hydraulic prop to the roof through pumping pressure. A larger initial support force can make the single hydraulic prop reach the working resistance faster, reduce the amount of sinking of the roof, and prevent the early separation of the roof from breaking. According to the ministerial requirements, the initial support force of a single hydraulic prop (to be oo ~) is not less than 90kN. Then how to calculate the initial support force of a single hydraulic prop, today we use an example to illustrate.
Calculation method of initial support force of single hydraulic prop:
For example: The initial support force of a single hydraulic prop is 100KN, the column diameter of the single hydraulic prop is 100mm, and the unit of the single hydraulic prop table is pa. So how to calculate the initial support force of a single hydraulic prop?
Answer: The data displayed by the pressure gauge is the pressure, divided by the cross-sectional area of the hydraulic prop, and 100mm is converted into 0.1 meters, that is (0.1 / 2) * (0.1 / 2) * 3.14 is that N / m2 is not enough to 100KN. That's 100000N.
