Abstract EN
Overburden strata movement in large space stope is the major reason that induces the appearance of strong mining pressure.
Presplitting blasting for hard coal rocks is crucial for the prevention and control of strong pressure in stope.
In this study, pressured water coupling blasting technique was proposed.
The process and effect of blasting were analyzed by orthogonal test and field practice.
Results showed that the presence of pressure-bearing water and explosive cartridges in the drill are the main influence factors of the blasting effect of cement test block.
The high load-transmitting performance of pore water and energy accumulation in explosive cartridges were analyzed.
Noxious substances produced during the blasting process were properly controlled because of the moistening, cooling, and diluting effect of pore water.
Not only the goal of safe and static rock fragmentation by high-explosive detonation but also a combination of superdynamic blast loading and static loading effect of the pressured water was achieved.
Then the practice of blasting control of hard coal rocks in Datong coal mine was analyzed to determine reasonable parameters of pressured water coupling blasting.
A good presplitting blasting control effect was achieved for the hard coal rocks.
