Decreasing the ratio of mining to digging, optimizing the blasting parameters, improving the blasting plan, reducting the specific explosive consumption ad the dosage of the cement for supporting, appropriate investment for engineering are the effective measures for decreasing .

The conditions of city environment to restrict blasting engineering are introduced into the standard of evaluating the blasting plan.

Comprehensive evaluation model based on gray correlative analysis and its application to selecting blasting scheme

Blasting scheme and safety measure of close quarter and high slope

The influence of blasting scheme on the cost of chamber blasting is discussed.

To reduce the vibration from blasting and ensure the safety of flood-control wall,the controlled blasting program of non-electric defonation circuit,span-by-span collapse and multilayer delay was adopted.

Reasonably choosing blasting program and designing blasting network in complicated geological conditions are adopted in the blasting.

Longhole controlled blasting techniques were applied and the coverage protective measures were taken during construction in accordance with technical specifications for water conservancy & hydropower and rock blasting,thus to ensure safety of the EHV power supply line and re- lated towers in the emergency water supply channel of the Beijing-Shijiazhuang section excavation work

During the construction of the Shunping section of the South-to-North Water Transfer Project,the amount of rock blasting is enor- mous.

Here the auther adopted scientific design and actualized for amour blocks blasting project,aimed at the character and difficulty of rock blasting project in the scurviness tropic desert.
