Research on Drilling Rate Optimization of a UCS Identification System While Drilling for Coal Mine Roadway Roofs

In this paper, to identify the roof unconfined compressive strength (UCS) in the process of coal mine roadway support in real-time and optimize the real-time drilling speed while drilling, this paper proposes and establishes a drilling test method for assessing the uniaxial compressive strength (UCS...
