Longwall mining remains the most efficient method for underground coal extraction worldwide, accounting for over 50% of underground production in major mining nations like Australia, the USA, and China. As global energy demands fluctuate, the industry is shifting toward Deep Mining and Smart Automation.
Today's commercial landscape demands equipment that can handle extreme depths (often exceeding 1,000 meters) and harsher geological conditions. Companies are no longer just looking for "cheap" equipment; they are seeking Cost-Efficiency—a balance between affordable capital expenditure and low maintenance costs through high-quality seals and reinforced hydraulic systems.
Transitioning from 30T carriers to 80T heavy-duty hydraulic support trucks to minimize transportation cycles in fully mechanized mines.
Explosion-proof diesel engines and ultra-high pressure rubber hoses that meet stringent ISO9001 and IRIS certifications for underground safety.
Auxiliary transportation systems are becoming autonomous, utilizing LWC chock carriers with real-time pressure and speed monitoring.
Founded in 1996, Kelong New Materials is a leading technological innovator specializing in hydraulic seal sets, high-pressure hoses, and coal mine auxiliary transportation equipment. Our products serve diverse sectors including Coal Mining, Civil Aviation, High-speed Rail, and Wind Power.
