Demolition blasting practice of an industrial workshop within the boundary of an open-pit mine
Withthe development of Tongman open-pit,there are nearly 13200m2 industrial buildings in the stope for historical reasons.In order not to affect the normal progress and development of the whole open pit,it is necessary to complete the demolition of related industrial plants as soon as possible to create conditions for the mining production stripping.After on-site investigation,it is found that the design of industrial workshop in this area is complicated and the construction standard is high.The use of excavating equipment on site will lead to low efficiency of mechanical equipment and can not guarantee construction safety.After many plans demonstration,it is agreed that demolition blasting is an efficient and safe construction plan.In order to complete the large-scale demolition blasting,the company Blasting Technical Group and the blasting company carried out in-depth discussion and research,and solved the production problems of the enterprise,for the same kind of open-pit mines encountered similar production problems to find a solution.This blasting experience is worthy of similar mines for reference.
