The single hydraulic prop is also called a single post, which is different from the hydraulic prop support in its structure. For a long time, the safety of coal mines has always affected the hearts of miners and their families, and the topic of mine safety mining has also become the focus of increasing attention.
When the adjustable props is automatically unloaded and lowered, the unloading valve fails, the mechanical deformation of the surface of the pillar is significant, and the mechanical scratches affect the homework, it is necessary to lift the well in time for maintenance. The adjustable props is suitable for horizontal or gently inclined coal seams with an inclination of no more than 25°. After safety measures are adopted, it can also be used in coal seams between 25° and 35°. The bottom plate should not be too soft and the periodic pressure of the top plate is significant To directly top the surrounding rock that is easy to collapse, use a single column on the working face where the floor is too soft, the geological premise is complicated or layered, and corresponding safety measures should be taken.
The hydraulic prop is matched with the metal hinged top beam, which is used in the support of the general mining face. The uprights and hinged top beams of the working face must be numbered, and the numbers should be entered into the row; segmented contract erection and treatment should be adopted. This is the hub of roof management.
We should pay more attention to these matters in our daily production. This not only improves the acrow prop production efficiency, but also prolongs the service life of the acrow prop. At the same time, it also provides a more favorable guarantee for the safe production of Panbo miners. The hydraulic prop is a kind of support product for mining. The use of the single hydraulic prop brings convenience to coal mining and also provides a guarantee for the personal safety of coal mine workers under the mine.
In the underground support, attention should be paid to the damage of the acrow prop, and inspection and maintenance should be carried out on schedule. The pillars of a uniform type and specification must have the same working function during operation, and each pillar must reach its initial supporting force when lifting the pillar. The use of single hydraulic props cannot be mixed with props of different properties and specifications.
Remind everyone to strictly follow the operation process to improve safety awareness.
