A carbon dioxide fracturing device is a piece of equipment that uses carbon dioxide to fracture rock in mining, as an alternative to blasting.

　　Carbon dioxide splitting equipment is specifically designed and developed for the mining industry, mainly used for mining, quarrying, rock splitting, stone yards, and metal mine splitting and mountain opening. It is an excellent alternative to explosive blasting.

　　Due to stricter safety and environmental regulations, the state's control over explosives is becoming increasingly stringent. Civilian enterprises find it difficult to obtain explosives for production, and some enterprises have even stopped production, causing significant difficulties and directly impacting economic efficiency.

　　When encountering large faults, karst, or fractured zones, explosive charges should be avoided as much as possible, or auxiliary charges should be used. In river diversion and excavation of road cuts and ditches, the water level elevation should also be considered. In all cases, the use of excessively large minimum resistance lines should be avoided. As long as the excavation workload, construction period, and other conditions permit, multi-layer, multi-row, and distributed charges should be used to replace a single large charge. The determination of a reasonable charge spacing can ensure that no rock ridges are left between two charges while fully utilizing the explosive energy. The charge spacing is often determined based on the minimum resistance line and the blasting effect index, and is related to the blasting type and topographic and geological conditions. The values listed in Table 12-4 can be used as a reference for determining the charge spacing. The minimum resistance line and blasting effect index in the table should take the average value of adjacent charges. Calculation of the charge amount: 1. Standard explosive consumption q value (1) The standard explosive consumption q can be selected according to Table 12-5. (2) When the blasting scale is large, blasting funnel tests should be conducted to determine the q value. (3) The standard explosive consumption can be calculated using the following empirical formula and modified with equation (12-15), that is, concentrated charge.
