Abstract

The invention provides a water pressure blasting construction method for a steeply inclined thin ore body. The water pressure blasting construction method comprises the following steps that a blasting free surface is constructed on the steeply inclined thin ore body, a plurality of blast holes are constructed in the blasting free surface, a certain angle is formed between the extension direction of the blast holes and the horizontal direction, explosive cartridges and water bags are installed in the blast holes, openings of the blast holes are blocked through tamping plug, the explosive cartridges are electrically connected with an electronic detonator detonating system, the electronic detonator detonating system is checked, the safety of the electronic detonator detonating system is confirmed, then detonating is conducted according to the sequence from outside to inside, the ore body after blasting is checked, the safety of the ore body is confirmed, deslagging operation is conducted, and construction is completed. According to the water pressure blasting construction method, blasting construction efficiency is improved, and the comprehensive cost is reduced.

Description

technical field [0001] The present application relates to the technical field of mining, in particular to a hydraulic blasting construction method for steeply inclined thin ore bodies. Background technique [0002] Blasting technology is widely used in tunneling, urban construction and other fields. Conventional blasting technology mostly uses air as the blasting medium, and the blasting process is difficult to control and has high risks. [0003] For this reason, people propose hydraulic blasting technology, which uses water as an energy transfer medium to transmit explosion energy and pressure to break the surrounding objects to be blasted. It has uniform energy transmission, high utilization rate, and can effectively improve the quality of blasting molding. Etc. [0004] At present, the blasting technology used in the field of mining is mostly conventional blasting technology, and hydraulic blasting technology is rarely used. However, conventional blasting causes defects...
