CJ-130 two-way pneumatic DTH is a new type drilling machine, which has been successfully applied to the construction in the field of anchor engineering. However, its design functions were affected in a certain degree by lacking of the operation rules and regulations. On the basis of introduction of the construction equipments and processes of CJ-130, the drilling rules and parameters were analyzed and the key operational points and notes were summarized in order to provide a technical guidance in the future geotechnical anchor engineering construction and provide some valuable references for later researchers.
