1. Client’s Trouble: Quarry Forced to Stop Production
A limestone quarry owner in Shanxi faced a tough operational dilemma. Strict local explosive control policies made explosive blasting impossible, leading to a full site shutdown. The quarry’s limestone features a Mohs hardness of 3 with loose rock texture, but the client had no compliant, efficient rock-breaking equipment to replace traditional blasting. Long-term suspension caused huge economic losses, and he was eager to find a safe, approval-free mining solution to resume production.
2. Professional Communication & Customized Solution
After in-depth communication with the client, our technical team analyzed the on-site rock properties and tailored a targeted CO2 fracturing solution. We explained that the low-hardness limestone is extremely suitable for our physical CO2 fracturing equipment. Different from dangerous civil explosives, the device relies on CO2 physical phase change: sealed carbon dioxide vaporizes instantly, expands 600 times and releases 300MPa high pressure to crack rocks stably with no shock waves or vibration. We conducted an on-site test with standard layout (140mm hole diameter, 2.5m row spacing, 7m hole depth). Only 10 fracturing tubes cracked massive rocks completely, achieving an output of 500m³ (1500 tons) in a single test.
3. Excellent Application Effect & Capacity Upgrade
The on-site test fully verified the equipment’s safety and efficiency. With no explosives, hazardous chemicals or potential safety risks, it completely solves the explosive ban construction problem. Deeply impressed by the stable breaking effect, the client immediately purchased 30 additional fracturing tubes. Now the quarry arranges two rounds of fracturing operations every day, with a stable daily output of 5000m³. The solution successfully helped the client resume full production, cut idle loss costs and achieve a substantial increase in mining efficiency.
