For a long time in the coal mine site frequently accidents, what is the cause of the accident? Often is the worker does not pay attention to, the equipment has regular maintenance and so on a series of unimportant little things, if you can pay more attention to the side, can give the coal mine workers under the mine safety added a guarantee. Here are some safety measures for single hydraulic props that are expected to help coal miners.
Single hydraulic prop
For a long time, the safety of coal mine has always affected the miners and their families, and the safety of coal mine has become the focus of people's attention. In the prop of automatic unloading column, unloading valve failure, the surface of the prop mechanical deformation is significant, mechanical abrasion affects the work, it must be timely out of the well for maintenance.
A single hydraulic prop, also known as a single column, is different from a hydraulic support in its structure. Individual hydraulic prop is suitable for the level in the dip Angle is not more than 25 ° or slowly inclined coal seam, after using the security measures, as well as used in the coal seam of between 25 °, 35 °, request not too soft, periodic roof pressure significantly, immediate roof caving easily premise of surrounding rock, on the floor is too soft, complex geological premise or layered face using a single column, take corresponding safety measures. It is matched with metal hinged roof beam and used in support of mining face. Working face column and articulated roof beam must be numbered management, the number into the row; Want to adopt section contract erects and management. This is the hub of roof management.
We should pay more attention to these matters in daily production life, which not only improves the production efficiency, but also prolonging the service life of the single hydraulic prop, but also provides a more favorable guarantee for the safety of miners. The single hydraulic prop is a kind of mine support product. The use of single hydraulic prop brings convenience to coal mining and also adds a guarantee to the personal safety of coal miners.
In underground support, should pay attention to the damage of the single hydraulic prop, regular inspection and maintenance. Unified type, specification of the prop, in the operation to make its working function is consistent, when raising the column must ensure that each column to achieve its initial support. The use of single hydraulic prop, can not be mixed with different properties, specifications of the prop.
To ensure personal safety, we should not only pay attention to whether the equipment should be repaired, but more importantly, buy a good quality equipment. I recommend Shandong China Coal Group.
