Preliminary Experimental Study on the Cross-Specimen Borehole Applicability of Identical Rock-Mass Characteristics Using Built-In Multi-Sensor MWD Monitoring for a Roof Bolter

Built-in multi-sensor measurement-while-drilling (MWD) modules on roof bolters can record torque, thrust, rotational speed, and displacement during drilling. This study examines whether identical rock types produce consistent MWD responses when tested through different boreholes in separate composite specimens. Three l...
