• Description:
  The drilling involved in the roof bolting operation in coal mining could not only generate excessive amounts of respirable coal and quartz dusts but also could encounter work interruption. Based on laboratory drilling tests, a comprehensive drilling control algorithm was developed to increase the drilling energy efficiency and to reduce the generation of respirable dust. The drilling rate deducted from test results is introduced in this study while considering the bit wear condition. The ratio between specific energy and rock uniaxial compressive strength is used as the index to determine the rational drilling control in this algorithm. In this paper, a drilling control algorithm for achieving a rational drilling bite depth is demonstrated. By adapting this drilling control algorithm, the drilling efficiency and bit condition can be monitored in real time, so the system can maintain a relatively high energy efficiency with less respirable dust generation and avoid drilling failure.
