18 Study and Construction of Experiment Table of Drilling at Any Position of Rock Sample

This paper introduces a drilling experiment table for laboratory use. This table can simulate drilling process and realize hydraulic feeding, rotating, and clamping rock sample. It can also realize stepless speed regulation for rotating system, and control drilling pressure accurately. The host power head can move in two-dimensional space. It forms a sectorial working face, therefore, it can drill at any position of rock sample. A multi-drilling parameters automatic measuring system which developed with configuration software has been also devised. The system can real-timely measure drilling pressure, rotational speed, depth of drill and drilling speed, etc. All the parameters and the real-time curves can be displayed on monitor. A database of the parameters can be built. And drilling reports can be generated.
