Information Management for Improved Blasting Operations and Environmental Control

摘要

A single blasting event can generate vast amounts of data. This information may be collected pre or postblast and individual ways may have requirement to be logged, processed, analysed, reviewed and reported eventually being archived. Collecting information during the blast is also of equal importance. The recording of information is critical to the blasting process, whether it be for planning purposes, statutory requirements or environmental compliance. The review and analysis of past data can play a key part in a blast's design. Statuary records must be held to preserve operational licences and as well maintained monitoring records are a vital defence for today's litigious society. In light of today's technology, the most efficient method of data management is by means of computerized database. This concept has been used to develop database system which is not only means of information storage, but also acts as an intelligent system as an aid for blast design, and analysis. The system allows the user to input all necessary information regarding blast design, site, explosive and weather details and covers all necessary statutory requirements. Vibration monitoring results are similarly in separate modules include safe charge weight determination and vibration prediction. On receiving such information, the system up-dates scaled distance relationship, diagnoses location variations and ultimately provides the blasting engineer with an interactive means to assist with planning future blasts. Additionally, information can be used for simulation and airblast and ground vibration reinforcement analysis. Similarly prediction of flyrock and safe zone for personnel and equipment can be indicted from this data. Similarly prediction of dust plume movement resulting from blasting can help controlling dust hazard. This information helps in better control and optimizing mining operations. Performance and cost of blasts can be monitored and appropriate blast designs for particular areas of different zones can be identified. Optimizing the blasting process involves drilling accuracy and efficiency, profiling exposed faces for mining applications, tailored loading explosives according to face profile and rock conditions at depth, and designing proper parameters, delay timing and initiation sequence.
