Under the global trend of sustainable development in the mining industry, Crawler DTH Drilling Rigs are transforming from traditionally high-energy-consuming equipment into key enablers of green mine construction through technological innovation. Their environmental evolution is primarily reflected in three major areas:
I. Emission Control Technology Upgrades
The new generation of rigs widely adopts high-efficiency diesel engines compliant with China National Phase III/IV emission standards, reducing nitrogen oxide (NOx) emissions by over 90% compared to older models. Our leading models are equipped with hybrid systems that automatically switch to electric motor mode during rig positioning and standby phases, achieving zero on-site exhaust emissions. Field test data show that hybrid technology can reduce annual carbon emissions per unit by approximately 45 tons. We will continue to advance research and development in line with market demands and national requirements to meet construction site emission standards and realize the vision of "green mining."
II. Integrated Noise and Dust Control
Through optimized hydraulic system pulsation control and composite soundproof enclosures, operation
al noise has been reduced from 115 dB to below 85 dB, meeting requirements for nighttime construction near residential areas. Dry dust collection systems have achieved an adoption rate of 80%. Utilizing a three-stage filtration design (cyclone separation + cartridge filtration + high-efficiency filter), on-site dust concentration is controlled within 5 mg/m³, significantly lowering the occupational risk of silicosis.
III. Resource Circulation Technology Applications
Intelligent lubrication systems save 30% of lubricant consumption and are equipped with waste oil recovery units. Automatic rod-changing systems reduce manual intervention by 70% while lowering component wear. Some mines are piloting the use of biodegradable hydraulic oil, which decomposes in soil within 180 days.
Industry Case Study: By fully transitioning to environmentally friendly DTH drilling rigs and integrating photovoltaic power supply systems, Indonesia successfully reduced the carbon footprint per ton of ore by 28% and obtained the International Council on Mining and Metals (ICMM) sustainability certification in 2023. It is projected that by 2026, the procurement share of rigs with environmental certifications will increase from the current 35% to 60%, becoming a benchmark for mining equipment procurement.
With the implementation of policies such as the EU Carbon Border Adjustment Mechanism (CBAM), environmentally friendly drilling rigs have shifted from a "technical option" to a "commercial necessity," reshaping global standards for mining equipment procurement.
