It is very important for drilling parameters test to better drilling parameters,design drill rig,research on drilling technology.

According to the rock characters in Lushan area, the new reasonable technique parameters of the diamond hit was designed and by using suitable drilling parameters and combinable low solid mass mud, great success had been obtained in hard rock big diameter and deep drilling.

The mutual relations of drilling parameter during petroleum drilling procedure and their effect on the drilling procedure were analyzed,and a model of the differential cost under unit drilling footage was presented.

This article studies a set of system for detecting the drilling parameters combined with HT-60 rotary spray rigs.

The ZCY series drilling parameters monitoring system is an high technologic result,combining computer techniques,monitoring techniques in combination with drilling technology,which monitors and records ten kinds of drilling parameters simultaneously.

The problems of serious cutter wear and segment dislocation are solved by adopting proper cutting tools and selecting reasonable boring modes,boring parameters and reasonable simultaneous grouting parameters,as well as by strengthening cutting tool maintenance.

Through form observation to rock blocks,excavation parameter analysis and geological window measurement,the rock mass condition can be synthetically estimated.
