On the following pages, you will see how our information management systems are helping our coal customers tackle their unique challenges.
Boretrak Used to Detect Hole Deviation and Toe Burden
DynoConsult was called in to help reduce coal loss from blasting and determining why there were inconsistent results of face movement. There are several factors that can contribute to this problem. Some may not have an easy solution, but could be minimized by determining some of the dimensions that are taken for granted, such as face burden and borehole deviation.
Decline Design for Underground Coal
This underground mine in the Southeast United States wanted to develop a decline from one level of the mine to another in order to shorten haulage distances. Lacking expertise within the company for the development of blast design for declines, the customer contacted DynoConsult® for assistance.
DYNO 42™ Used for Vibration Control
DYNO 42 used to pinpoint best delay sequence for vibration reduction
Highwall Stability Improvement through Less Blast Vibration and Displacement
Highwall deterioration leads to potential hazards
Is One Booster as Good as Two?
This company requested that DynoConsult® conduct velocity of detonation measurements to determine if one 400 gram booster would be sufficient for the product to reach steady state velocity.
Laser Profiling for Blast Design
To support this customer, DynoConsult provided field profiling services and data analysis for four cast blasts at this operation. Basic shot design based on 3D burden measurements was provided to the customer for final adjustments based on updated bench conditions for drilling operations.
Using Existing Equipment for New Test Programs
Alternative methods to measure p-wave velocities, record near field vibration levels from cast blasts and perform down hole seismic studies to quantify highwall damage
