For a long time, accidents have occurred frequently on coal mine construction sites. What is the cause of the accident? It is often because workers do not pay attention, whether the equipment is regularly maintained, and a series of small things that do not care. If you can pay more attention to your surroundings, it can provide a guarantee for the personal safety of the coal miners under the mine. The following are some safety measures for the single hydraulic prop, hoping to help the coal miners.
Single hydraulic prop
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 prop is automatically unloaded and lowered, the unloading valve fails, the mechanical deformation of the surface of the prop is significant, and the mechanical scratches affect the homework, it is necessary to lift the well in time for maintenance.
Some Safety Measures Of Single Hydraulic Prop
The single hydraulic prop is also called a single post, which is different from the hydraulic support in its structure. The single hydraulic prop is suitable for horizontal or gently inclined coal seams with an inclination angle of not more than 25 °. After the safety measures are adopted, it can also be used in coal seams between 25 ° and 35 °. The bottom plate must 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. It is matched with metal hinged roof beams and is used for supporting in 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 precautions in the usual production life, which not only improves the production efficiency, but also prolongs the service life of the single hydraulic prop, and also provides a more favorable guarantee for the safe production of miners. The single 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 single hydraulic prop, and inspection and maintenance should be carried out on schedule. The props of a uniform type and specification must have the same working function during operation, and each prop must reach its initial supporting force when lifting the prop. The use of single hydraulic props cannot be mixed with props of different properties and specifications.
To ensure personal safety, not only pay attention to whether the equipment needs to be repaired, but more importantly, buy a good quality equipment. I recommend Shandong China Coal. The quality of Shandong China Coal products is good, the technology is mature and reliable, and it is trustworthy.
