| Abstract: | The supporting system selection is analyzed in mining small piece of 2.4 - 3.8 m middle and high seam. Using single hydraulic supporting system mined by one time is reasonable. According to the size of sigle hydraulic postes, The single hydraulic post improvement with height added is pointed out. A good demonstration has been set up in mining small piece of 2.4 - 3.8 middle and high seam by practice. |
