In recent years, anchor drilling machine has been rapidly promoted in China's coal mine industry, which has become an important means of coal mine roadway support. Quanzhou Qianshan Machinery Co., Ltd. conforms to the market demand and is a manufacturer specializing in producing anchor drilling machine. The production practice shows that adopting Bolt support can not only save wood and steel, reduce project cost and speed up rate of advance, but also improve roadway support condition and ensure safe production, it has obvious social and economic benefits.
The primary problem to be solved in the Bolt support work is to finish the drilling work of the bolt hole on the roof of the roadway efficiently. Therefore, providing ideal light drilling equipment becomes the key factor for the rapid promotion of Bolt support. Many scientific research institutions and manufacturers, combined with China's national conditions, have successively developed or imitated various light anchor drilling machine, promoting the development of China's anchor drilling machine technology. However, our research on anchor drilling machine is still in the initial stage. Through research and investigation, analysis and discussion, we believe that it will be beneficial to the improvement of anchor drilling machine and the development of new anchor drill in our country.
