PX-ZYWL-4600D Omnidirectional Drill Rig | Underground

Product Overview

The PX-ZYWL-4600D Omnidirectional Engineering Drill Rig is a versatile drilling platform for underground coal and hard-rock operations requiring boreholes for gas drainage, water injection and pressure relief. With an output torque range of 4600–1140 N·m and rotation speeds from 60 to 190 r/min, the rig delivers controlled drilling across varied strata. Rated drilling capacity reaches 300 m depth or 780 mm diameter depending on borehole design, and the 55 kW installed power supports continuous operation underground. The 4600D can be configured to project requirements, making it a practical asset for mines standardizing on a flexible, multi-purpose drilling fleet.

Product Description

The PX-ZYWL-4600D is engineered around a modular omnidirectional structure that allows drilling at multiple angles to match seam and strata conditions. Its torque range of 4600–1140 N·m lets the rig start holes efficiently in harder ground and maintain controlled advance in softer formations, while the 60–190 r/min rotation band gives operators flexibility across bit sizes and rock types. The drilling capacity of 300 m depth or 780 mm diameter covers a wide spread of drainage and exploration boreholes, and the 55 kW power pack is matched to underground electrical supply and ventilation constraints.

Beyond straight drilling, the rig supports water injection and pressure relief duties that help mines manage gas and rock stress hazards. Rod handling, feed travel and clamping functions are arranged for efficient tripping, and the machine weight of approximately 6000 kg keeps it transportable within underground workings. Multiple torque and depth classes are available across the PX-ZYWL series, so the 4600D can be specified as part of a matched fleet. Final configuration, including feed length, control mode and auxiliary equipment, is defined with the project team to suit site geology and drilling schedule.

Technical Specifications

Applications

The PX-ZYWL-4600D is applied in underground mines for gas drainage boreholes, water injection for dust control, pressure relief drilling and geological exploration where seam conditions change frequently. Its omnidirectional capability lets crews position holes at the angles required by the mine plan without excessive rig repositioning. Operators benefit from a machine that matches the productivity of a medium-duty class rig while retaining the flexibility to handle multiple drilling programs with one platform.
