It is the first time that the expert control theory is applied to the blasthole drill control described in the paper, where the expert control structure and strategy for blasthole drill control are studied. At last, an integrated software for the expert control is compiled with Borland C++4. 0 under the operation system of Windows95. It includes the following functions: the simulation for control theory and control structure, the realization of the blasthole drill control.

作者用Borland C++4.0在Windows95环境下编制了专家控制的集成软件系统，一方面对控制方案及算法进行了仿真研究，另一方面针对YZ-55型牙轮钻机的实际工况设计了软件控制功能；并按照牙轮钻机钻进控制的专家控制体系与控制策略，在实验室对控制算法与控制硬件系统进行了实验验证。

Dremel Minimite Drill: If you're going to get serious about bead-making or polymer clay you may want to invest in one of these small drills. I use mine for drilling holes in baked beads.
