Rock breakage gas generator and gas generating agent rock breaking method

Abstract

The invention provides a rock breakage gas generator and a gas rock breaking method. The rock breakage gas generator comprises a gas generation pipe, a trigger device and a starter independently dismounted; the starter comprises a start pipe, a start head and an electric conducting lead; the start pipe is filled with a first gas generating agent; and direct-current starting current generated by anexternal electric exploder is started by the electric conducting lead to ignite the first gas generating agent. The trigger device is filled with a second gas generating agent, which is ignited by energy generated by the first gas generating agent; and the gas generation pipe comprises an outer cylinder, and an inner cylinder supported inside. The trigger device is positioned in the inner cylinder; and the starter at least partially extends into the inner cylinder. The gas generation pipe is filled with a third gas generating agent, which is ignited by energy generated by the second gas generating agent. Shell materials of the gas generation pipe, the trigger device and the starter all adopt low-mass paper pipe bodies or plastic pipe bodies for holding; and the gas generating agents inside are located in a non-pressure constraint state, so that the safety is high. The construction operation is simple and feasible, free of the lowest-pressure limitation and high in efficiency, and automatically adapts to the strength of construction objects.

Description

technical field [0001] The invention relates to the field of blasting, in particular to a rock-breaking gas generator and a rock-breaking method for a gas generating agent. Background technique [0002] The current rock-breaking methods and technologies generally use traditional explosives for construction, but explosive blasting requires high blasting technology and is extremely unsafe. The government has very strict management of explosives, and many operating environments (such as residential areas, high-voltage lines, high-speed railways, etc.) cannot be used. Or the use of explosives is prohibited, and flying stones, vibration, noise, and toxic and harmful gases are likely to be generated during the blasting process. In recent years, carbon dioxide blasting technology has begun to rise. The plan is: fill a steel pipe made of high-strength alloy with liquid carbon dioxide, heat and ignite the activator built in the steel pipe through a conductive wire, so that the carbon...
