Abstract:
Provided are an expansion pipe for blasting and a blasting method therefor. The expansion pipe comprises a main pipe ( 1 ) of which the head and tail ends are provided with a first plug ( 3 ) and a second plug ( 4 ) and a branch pipe ( 2 ) which is fixed to the interior of the main pipe ( 1 ) by means of the first plug ( 3 ), wherein a gasification agent and an electric starter ( 7 ) mounted on the first plug ( 3 ) are provided inside the branch pipe ( 2 ), the other end of the branch pipe ( 2 ) is provided with a sealing plug ( 5 ), a connecting pipe ( 6 ) is further provided at the head of the main pipe ( 1 ), one end of the connecting pipe ( 6 ) is connected to a gas source or a water source and the other end penetrates through the first plug ( 3 ) to be in communication with the inner cavity of the main pipe ( 1 ). When the expansion pipe is used, a group of the expansion pipes are connected in a head-to-tail manner via fixing pieces ( 8 ), then a hole is punched at a blasting point, the connected and fixed expansion pipe group is placed into the hole, the opening of the hole is sealed with cement, and finally the electric starter ( 7 ) is started through a remote controller outside a dangerous range, and the gasification agent is ignited by the electric starter ( 7 ), causing water gasification or air expansion inside the main pipe ( 1 ), such that the expansion pipes are blasted.

Claim (Index 9):
The blasting method according to  claim 5 , wherein mass ratios of ingredients of the gasification agent are as follows: nitroguanidine of 45%, copper nitrate basic of 45%, ferric oxide of 5%, and ammonium perchlorate of 5%.
