Series static armor-piercing tests were carried out to validate the performance of the proposed tandem shaped charge and in the experiment it penetrated a reinforce concrete.

Used the norm penetration case,the quietly penetration has been done to the steel target plank which is equal thickness but different intensity,and the similar form craters ware be obtained.

Through these design ways, the valid length of jet and the penetration power of shaped charge were improved evidently.

Through using static blasting technology,installing temporary climbing frame and lifting plate,mining excavators and two blenders mix asphalt guarantee the temporary locking removement and safe and smooth construction of the permanent lock.

The selection of primary parameters of demolishing the foundation of air compressor in the coal mine by static fragmentation measure,implementation method and blasting results are presented.

Application of static blasting technology in reconstruction of old bridge;

Differential damping static blasting construction of Yingyaoshan tunnel rock boundary

The old beams are laterally removed manually,bridge piers are demolished by static blasting,and the construction scheme of jacking-in the framed structure is adopted.

Static demolition is a new\|type technology in construction,since it can break r ocks and reinforced concrete building projects,without shock,flying blocks,noise and pollution.

The principle of static demolition is putting into blasthole water-mixed tatter agent and then the building elements will be demolished noiselessly by the tremendous expansion.

The design and construction of static demolition in the R.
