The carbon dioxide fracturing device is a specialized equipment designed and developed for the mining industry. It is mainly used in mining, stone quarrying, rock splitting, stone quarrying, metal ore block splitting, and mountain excavation. It is an excellent device to replace explosive blasting.

Due to the strengthening of safety and environmental protection requirements, the state's control over explosives is becoming increasingly strict. Civilian enterprises can easily obtain explosives for production. Some enterprises have already suspended production, which has brought great difficulties to production and directly affected economic benefits.

When the carbon dioxide fracturing device encounters large faults, karst or fractured zones, the drug bags should be kept away from these geological structures as much as possible, or auxiliary drug bags should be set up for treatment. In river modification and the excavation of road cuts and ditches, the elevation of the water level should also be taken into consideration. (5) In all cases, the selection of overly 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 drug bags should be fully utilized to replace a single overly large drug bag. 3. Determination of the spacing a of the charge Packets A reasonable spacing of the charge packets can ensure that there are no rock ridges between the two charge packets, and at the same time, it can fully utilize the explosion energy. The FM in the drug packaging room 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 spacing of the medicine packets. The minimum resistance lines and blasting effect indices of various types in the table should be taken as the average values of adjacent drug packs. V. Calculation of Carbon Dioxide to the Loading Capacity of the Separator I. Standard explosive unit consumption q value (1) Standard explosive unit consumption q. It can be selected by referring to Table 12-5. (2) When the blasting scale is large, a blasting funnel test should be conducted to determine the q value. (3) The unit consumption of standard explosives can be calculated by the following empirical formula and modified by Equation (12-15), that is, the concentrated explosive package. . = 2 ·IV,(0.4+0.6n3)· Arrange (12-16) "medicine packets. ... . ·IV2·L(0.4+0.6n3)· Pendulum (12-17)216 Live Rock Blast Project.
