Abstract

The invention discloses a blasting construction method for blasting equipment. The blasting construction method comprises the steps: firstly a hole net is arranged, a first row of holes is formed in the direction of a free face, the hole diameter is larger than 90 mm, the hole distance is 500-1000 mm, the row distance between a second row of holes and the first row of holes is 500-1000 mm, and inthe same way, after hole forming, purging clearing is conducted on the blast holes; then the blasting equipment is sequentially put into the holes, the blast holes are stuffed with barriers, the blasting equipment is sealed in the blast holes, and the exteriors of the barriers are stuffed with quick-setting mortar; after the mortar is solidified, the blasting equipment is inflated and pressurizedthrough an air compressor and an inflating pipeline, and a pressure value reaches the initiation pressure; and finally after connection of an initiation circuit is completed and confirmed, ignition detonation is conducted. According to the method provided by the invention, the blasting implementation process is convenient, blasting controllability is high, blasting vibration can be reduced, greatprotection effect on the construction ambient environment can also be achieved, and meanwhile the blasting effect is ensured.

Description

technical field [0001] The invention relates to the technical field of blasting construction, in particular to a blasting construction method of blasting equipment. Background technique [0002] With the advancement of science and technology and the development of market economy, the use of blasting technology to implement engineering operations is becoming more and more widespread. In addition to the application in traditional mining, building demolition, tunneling, etc., it has also been used in engineering practice in some new places, such as quarry quarrying, dredging and blockage removal in steel plants, blasting in special locations, municipal engineering, Tunnel blasting, underwater blasting, etc. At present, the core content of the traditional blasting vibration reduction construction technology is to reduce the amount of charge in a single hole, use spaced charges, and reduce the distance between holes and rows. The above technical solutions are widely used, but t...
