EQUIPMENT & MATERIALS
Equipment and materials for each stage
Our R&D spans rotary cutting equipment and backfill materials suited to different underground conditions and tasks.
01High-pressure rotary waterjet mining system
Equipment for coal fragmentation, remote control and unmanned coal-face operations.
02Floor anchor-cable drilling rig
Designed for anchoring work in the floor of mine roadways.
03Rock rheology and in-situ stress testing equipment
A non-electric true triaxial rock rheology tester and a 3D hydraulic-fracturing stress measurement system.
04Equipment for thin and gently inclined seams
High-pressure side-cutting equipment for thin seams and unmanned coal handling systems for gently inclined or near-horizontal seams.
01Ultra-high-performance composite cement
Neat-paste compressive strength above 120 MPa.
02Two-component backfill and reinforcement cement
Neat-paste compressive strength above 15 MPa at 1 hour and 75 MPa at 28 days.
03High-expansion Portland cement for sealing gas drainage boreholes
Neat-paste compressive strength above 18 MPa at 7 days and expansion above 5%.
04High-performance sprayed coal-gangue mortar
Rebound below 6% and compressive strength up to 65 MPa.
05Rapid-hardening cement for roadway floors
Used to harden waterlogged and muddy underground roadway floors.
