In quarry operations, efficiency is a huge responsibility and task for many companies as it helps determine profitability of their plants. However, in today’s world, this important task is accompanied by many other responsibilities, thus not allowing enough time to be devoted to process improvements which ensure their sites are running at its optimum performance. In this presentation, we will define a "Connected Quarry," discuss the available technology that a "Connected Quarry" is comprised of, and through the means of technology, quarry operations are as efficient and productive as possible.


Karen Johnston
Jackson Kelly, PLLC

Managing Two Key Minefields of Operator Liability: MSHA Accident Investigations and Contractors on the Mine Site - Karen Johnston is a member of Jackson Kelly PLLC, resident in the Denver office.  She handles all aspects of the defense of safety and health cases involving both MSHA-regulated and OSHA-regulated facilities as part of the firm’s nationwide occupational safety and health practice group.  She counsels mine operators and general industry employers with respect to prevention and avoidance of liability under the Occupational Safety and Health Act and the Federal Mine Safety and Health Act, as well as the Safe Explosives Act.  She also handles all aspects of the defense of enforcement actions arising under those statutes, including both administrative and civil litigation.  She conducts seminars and training sessions on enforcement and discrimination topics under various state and federal safety and health statutes. 

This session will provide an overview of the two most common areas of legal liability for mine operators – accidents and contractor behavior – and provide some tips on how to manage each to minimize liability.  With regard to accidents, we will discuss how to handle, and hopefully limit, liability by knowing what to expect and what to do in an accident investigation conducted by MSHA. Using examples pulled from Ms. Johnston’s experience representing mine operators in serious and fatal accident investigations, the discussion will give operators insight on how to limit liability while managing the investigation process.  Another area of significant potential liability for mine operators is contractors, given MSHA’s authority to issue a dual citation to the mine operator for violations committed by a contractor.  Ms. Johnston will discuss how to manage contractor compliance and safety on the mine site, including discussion of the mine operator’s legal obligations when it comes to contractors and MSHA’s recently amended workplace exam rule.

Eric Gerst

Downstream Benefits of Optimized Drilling - Eric Gerst is employed by FLANDERS in Evansville, IN as a Global Business Development Specialist – Drills.  He spent most of his career in the explosives industry, 16 years as a Senior Technical Representative for The Ensign-Bickford Company working in Arizona, New Mexico, and the Illinois Basin and 7 years with Dyno Nobel prior to joining Flanders in 2015.  He works on developing markets and sales for FREEDOM for DRILLS automation and other drill optimization products in the eastern US and Canada.

Expanding blast patterns to near the limit of an explosives’ ability to do the necessary amount of work is a common practice to reduce drilling and blasting costs.  Choosing less expensive explosives such as ANFO vs. emulsion, bulk product versus packaged product, etc. are also common cost savers.  Both practices are only effective if the pattern geometries are accurately drilled.  However, will pushing the limits on pattern sizes and explosive products produce consistent results at the face, minimize oversize, produce superior fragmentation, and improve crusher throughput?  Sometimes, but no amount of explosives can overcome a poorly drilled pattern.  Knowing the probable outcome of any changes in drilling and blasting is valuable in achieving success.
