With the vigorous development of the mining industry at home and abroad, the mine scale and the mining quantity are increased year by year, and large rock drills are increasingly used in mining. Large rock drills, including open-air and downhole drilling rigs, generally consist of a chassis, a drill boom, a propeller, a control system and a rock drill (open-air drilling rigs generally also have a dust-catching system). The hydraulic motor has the characteristics of being matched with a high-efficiency host, adopting a propeller with high thrust and a slewing mechanism with high torque, generally adopting a hydraulic technology and the like. The application of the rock drilling rig is an important way for improving the mining speed, and is an important measure for reducing the labor intensity, improving the labor condition and improving the labor productivity. With the continuous improvement of the rock drilling and blasting process and the enlargement of the roadway working face, the large rock drilling rig shows the superiority more and more in production and construction, and the requirement on the rock drilling rig is higher and more in the practical application process.
Compared with a common rock drill, the large-scale rock drill has larger working load, stronger vibration and higher requirements on the antifriction performance and the adhesion performance of oil products. With the development of rock drilling equipment technology and the expansion of application fields, a special pneumatic rock drilling machine oil is urgently needed, and the special pneumatic rock drilling machine oil is required to have outstanding adhesion performance, excellent extreme pressure wear resistance and friction reduction performance, and good rust prevention, corrosion prevention and emulsification performance. Because the molybdenum salt has obvious antifriction effect in the lubricating oil and can be used as an excellent antifriction agent, the molybdenum-containing pneumatic rock drilling machine oil can be developed to lubricate rock drilling equipment under severe working conditions, particularly large rock drilling rigs.
Researchers at home and abroad have completed some highly effective work on rock drilling machine oil, but still have some defects.

Chinese patent CN200810101297.5 discloses a lubricating oil composition for pneumatic tools, which can be used for rock wind drilling machines, rock chisels and rotary pneumatic tools, has better rust-proof, corrosion-proof and emulsifying properties, and does not mention antifriction properties; chinese patent CN201310619015.1 discloses an improved pneumatic tool oil composition, which has good extreme pressure, rust prevention, friction reduction and wear resistance effects, but the embodiment of the improved pneumatic tool oil composition is not verified by oil detection and analysis results, and the emulsifying performance required by rock drilling machine oil is not mentioned.
