The detonating devices commonly used in tunnel engineering include nonel tube and carbon dioxide blasting device. Nonel tube is an ideal blasting equipment for tunnel blasting, which has the characteristics of antistatic, noise-resistant, water-resistant, impact-resistant, fire-resistant and long explosion propagation distance, and is suitable for gas-free tunnel blasting. Carbon dioxide fracturing device uses liquid carbon dioxide to gasify and expand when heated, and quickly releases high-pressure gas to crush rocks or coal, which overcomes the shortcomings of explosive blasting mining and presplitting to crush ore bodies with great damage and high risk.
