Water-Jet Coal Seam Slotting and Pressure Relief Device_Reaming-Type Permeability Enhancement System_Complete Equipment_Products and Solutions_Shandong xiangde Electromechanical co., ltd

Product Introduction

This equipment is specifically designed for coal seam slot cutting and pressure relief operations in complex geological conditions in underground coal mines. It integrates ultra-high-pressure hydraulic cutting, coal seam water injection, gas drainage, and stress release. Utilizing modular hydraulic drive with a maximum pressure of 60 MPa, and equipped with an intelligent control system and explosion-proof structure, it precisely performs deep coal seam slot cutting, reducing stress concentration in the coal mass and mitigating gas outbursts. High-pressure water circulates to flush the borehole, remove coal debris, wet the coal seam, and improve ventilation and operational safety. The tracked chassis adapts to narrow roadways, while forced lubrication at the power end and multiple safety protection devices ensure long-term stable equipment operation. It is a key equipment for achieving efficient coal seam pressure relief, advanced gas control, and safe mining operations.
