Abstract

The invention discloses a stone shallow hole blasting control method applied in a town and belongs to the technical field of blasting. The method comprises the following steps: dividing areas, excavating shock-absorbing ditches in a bench manner in different areas, arranging blast holes, drilling, loading and blocking, designing a blasting network, blasting area covering and building a vibration monitoring system. Due to the adoption of the method, the problem that a routine blasting manner is not permitted to complete construction in a city downtown and under a special environment is solved. The stone shallow hole blasting control method is proved to be effective in controlling both the blasting seismic effect and the harmful influence of scattering objects and the like, and in attenuating blast waves, thereby ensuring the construction safety.

Description

technical field

[0001] The invention belongs to the technical field of blasting, and in particular relates to a controlled blasting method for shallow holes in stone cubes in cities and towns. Background technique

[0002] With the rapid development of my country's economy, more housing construction will be carried out in urban downtown areas with dense population and many buildings. In some areas that are mainly built on the mountain, stonework excavation is often encountered during foundation excavation. In the past, manual chiseling and mechanical excavation were often used, which was far from meeting the needs of construction speed. Therefore, the shallow hole control of urban stonework Blasting technology came into being.

[0003] At present, in urban downtown areas and special environments, scattered objects and earthquake effects are often produced during the construction of shallow hole controlled blasting of stonework in cities and towns, which has adverse effects ...
