The construction project of the expressway from Nanxi to Huangshi in Yunyang County
The project site is located in Huangshi Town, Yunyang County, Chongqing City
The ore mined in this project is mainly used for the supporting construction of high-speed railways
The total volume of the project has reached 600,000 cubic meters. In the early stage, mechanical mining was always adopted, which was costly, difficult to construct and had a low output.
On March 28, 2020, Chongqing Chuangpuda Machinery Technology Co., Ltd. conducted an investigation of the construction site and tested the cracking effect caused by the expansion of carbon dioxide gas on the spot. The final cracking effect was very satisfactory, and the customer immediately decided to use carbon dioxide cracking.
Since the customer adopted carbon dioxide fracturing, the mining volume has been greatly increased. While the cost has been reduced, time has also been significantly saved. On average, the volume of each fracturing pipe can reach about 50 cubic meters, and the safety factor of the construction site has been greatly guaranteed.
