There are several technical colleges around the country that educate their students specifically on the use of explosives for blasting in the mining industry. One of these is Bridgemont Community and Technical College in Montgomery, WV. LTI recently teamed up with industry partner RAM, Inc. in an effort to supply equipment and training to Associate Professor and Blasting Program Coordinator, Brian Wingfield and his current class of students.
“After discussions with the Blasting Program Coordinator at Bridgemont, I knew this system would be an excellent fit with the current curriculum development,” said Robert McClure, RAM President.
The Impulse 200 laser rangefinder and corresponding software package were secured with the assistance of McClure. Instructions were given in basic laser principles, proper set-up, and alignment with mine highwall faces. Students generated various face profiles to become familiar with laser techniques and software capabilities. Blasthole offsets and angles were determined given burden design criteria.
The instruments emit a series of eye-safe laser pulses and use "time-of-flight" to calculate the slope distance to a mine highwall. An electronic tilt sensor also measures inclination, which allows these units to compute horizontal and vertical distance as well. Students also compared differences in zero off-set burdens by profiling a flat surface at 100’, 200’, and 300’ distances. The results were summarized by the students and forwarded to RAM and LTI, Inc.
“Bridgemont Community and Technical College is delighted to have the opportunity to expose our students to the newest technologies and strengthen our ties with companies involved in the blasting industry,” said Brian Wingfield, Blasting Program Coordinator. “The assistance we received is critical in the development of new blasting technicians our program is designed to graduate.”
Bridgemont awards one-year certificates and two-year associate degrees in many fields including engineering technology, advanced manufacturing, business and health management, dental hygiene, diesel technology, computer information technology, digital design and welding. Customized training is available at both the Montgomery and South Charleston campuses, or at company sites through the workforce development unit.
