Double-Boom Roof Cutting Drill Rig_Coal Mine Crawler-Mounted Hydraulic Roadway Drilling Rig_Drilling Rig Series_Products and Solutions_Shandong xiangde Electromechanical co., ltd

Product Introduction

This series of drilling rigs is designed as narrow-track equipment for gob-side entry retaining in coal mining faces, sidewall and roof bolt support construction, geological exploration holes, gas extraction holes, water injection holes, pressure relief holes, and other engineering boreholes. With a minimum width of 700 mm and a tracked travel system, it offers excellent maneuverability and is available in both single-arm and dual-arm configurations. The dual-arm roof cutting drilling rig is designed for parallel front and rear operations, enabling mechanical construction of various boreholes over a wide range in roadways through adjustments of the dual arms in both front-rear and left-right directions. The dual arms can operate simultaneously or independently. The drilling arm can move laterally, enhancing drilling flexibility and accuracy, ensuring boreholes follow preset trajectories and enabling precise roof cutting along pre-split cutting lines, thereby significantly improving roadway formation quality.
