The hydraulic prop plays an inestimable role in coal mine production.
The use of single hydraulic prop can make the working face high-yield and high-efficiency, reduce and eliminate the occurrence of roof accidents. At the same time, in the production process, strictly implement the operation procedures, operate carefully, and act according to the system measures and regulations, so as to play the advantages.
In the mining of thin coal seam, the support method based on single hydraulic prop has good working performance, and has its own advantages for roof management, and its supporting force distribution on roof is more uniform. The structure of acrow prop is different from that of hydraulic support.
It is matched with metal acrow prop, and can be used in general mining face support; it can also be used in local area of fully mechanized mining face, such as end or temporary support. The new or long-term unused hydraulic props should be lifted and lowered 1-2 times for the first time, and the air in the chamber should be drained before the support can be set up, because when the gas is contained in the inner chamber of the single body, the support will sink slowly after the initial support, resulting in the reduction of the initial support force and even the collapse of the support.
Safety production, reduce the occurrence of accidents, the role of single hydraulic prop, is indispensable.
