Given the characteristics of granite open-pit mines, MinGong Machinery (MGMA) provides a complete set of mining equipment covering cutting, assisted splitting, loading, hauling and transport, including double-blade quarry saws, diamond wire saws, chain saws, drilling equipment, forklift loaders, excavators and haul trucks. The solution is widely applicable to granite open-pit mines and dimension stone block production. It aims to help customers increase block productivity, reduce damage risks, lower secondary processing costs, and support efficient, sustainable mining operations.
Typical Application Scenarios
Large and small granite open-pit mines with intact ore bodies and few fractures
Mines supporting open-pit bench mining (layered extraction)
Mines planning to significantly increase production volume
Projects requiring smooth block surfaces and regular dimensions for direct export or further processing
Green mining standardization projects (replacing blasting or air-blasting methods)
Solution Features
Precision cutting, high recovery – Double-blade quarry saws achieve precise block separation with narrow kerf and low vibration, significantly reducing internal cracking. Block recovery rate can exceed 85%.
Efficient cutting, double-blade speed – Double-blade quarry saws improve cutting efficiency by more than 30% compared to single‑blade saws. Sawing speed is high (30 m/s in hard granite, 55 m/s in marble), with a daily cutting volume of 70–110 m³. The cut surface is smooth and clean, and block recovery exceeds 90%. Compared to traditional blasting, mining cost per cubic meter is reduced by 50–80 RMB, with no fly rock, no vibration, and safe, environmentally friendly operation.
Assisted splitting, avoiding violent breakage – Drilling equipment is used for pre-drilling or assisted splitting before block separation, eliminating blasting shock and preserving the natural texture and integrity of granite.
Efficient loading and handling – MinGong expertise – MinGong forklift loaders handle block loading, transfer and stacking, speeding up block removal to free the working face. The stable fork-and-carry method greatly improves transfer efficiency and reduces block damage compared to conventional excavator handling. Excavators are used for waste removal, overburden stripping and shaping, while haul trucks complete on‑site and off‑site transport. The entire equipment combination has clear division of labor and high operating efficiency.
Complete system, flexible matching – Based on mine capacity, ore body conditions and budget, we flexibly configure the number of cutting units, forklift tonnage and truck models, supporting both start-up needs of small-to-medium mines and expansion of large mines.
Service Support
MinGong Machinery (MGMA) provides full-process support from mine planning, equipment selection, on-site installation and commissioning to operator training, and offers standard warranty and genuine original parts supply for all main equipment. Equipment, tools and consumables (cutter bits, rails, drill bits, drill rods, etc.) are pre-stocked to reduce unplanned downtime.
