This article analyses the problem of excessively high temperature caused by environment tem¬perature of BM281 drilling machine hydraulic oil, solves this problem by improving performance of hy¬draulic oil cooling system, obtains remarkable economic benefits.

This text introduced the basic requestion of the hydraulic oil of drilling jumbo, and introduced the selection of hy¬draulic oil. Also, this text analyzed the contaminative approach of hydraulic oil, and advanced the measure of the prevent Hydraulic oil pollution.

For accelerating the construction speed of Tianxing iron mine and completing the project on time, high efficiency jumbo is planned to be used for mine development. Furthermore, operator can control the jumbo under FOPS canopy which can guarantee the operator safety.

In recent years,more and more high speed railway tunnels have been built in China. However,these high speed railway tunnels are basically constructed by drill and blast method assisted by hand held pneumatic drills and multi purpose operation platforms.Such equipment allocation mode has the
