Blast Monitoring with AirLink® LS300 Ensures Quarries Comply with Regulations

Deep Earth Logic is one of the nation’s largest blast monitoring companies. Established in 2012 and based in North Carolina, the company monitors the impact of controlled blasting specifically in quarries across the US.

Business Challenge

Quarry operators routinely perform controlled blasting in order to replenish their supply of gravel, fill and gradient used in the construction of roads, parking lots, and even cement. Legislation requires that such blasting be monitored to protect people, property and the environment.

Sierra Wireless Solution

Deep Earth Logic has established close working relationships with their clients allowing them to perform an important role as an independent third party that can not only perform all monitoring remotely, but assist their clients with public relations.

Deep Earth houses an Instantel seismograph along with the Sierra Wireless AirLink® LS300 rugged 3G gateway provided by Premiere Partner USAT Corp located in Chapel Hill, NC and houses the equipment in a cabinet which is mounted on a monitoring location. The monitoring locations are strategically placed around the quarry. Upon an “event”, the seismograph is triggered and the microphone and geophone are activated. The results are “locked in” and automatically transmitted via the AirLink LS300 to a back-end server. The data is then analyzed and sent on to clients and/or regulators. A typical quarry could have from 1 to 6 sensor units.
