Discussion on safe shot-point-distance of seismic exploration in urban areas

Along with an increasing requirement to HSE, the problems faced by seismic exploration in urban areas become unavoidable. The shot-point layout in urban areas must not only ensure the safety of the surrounding buildings but also avoid data qualitydecrease due to shallow seismic data missing in large area. At present, the safe distance obtained by operators is short of regional pertiaence, which cannot effectively strike a balance between safety and quality. Starting with safe vibration velocity allowed for buildings,the safe distance and explosive amount for different buildings are discussed. Good exploration effects are achieved..
