NSSGA gives OSHA additional info on proposed silica rule
NSSGA filed additional information and data with OSHA following the agency’s public hearings in March and April on a proposed respirable crystalline silica rule. OSHA’s proposed rule includes a new exposure limit for respirable crystalline silica and details widely used methods for controlling worker exposure, conducting medical surveillance, training workers about silica-related hazards and recordkeeping measures. It includes two standards: one for construction and one for general industry and maritime employment. OSHA says it currently enforces 40-year-old permissible exposure limits for crystalline silica in general industry, construction and shipyards. It believes the limits are outdated, inconsistent between industries and do not adequately protect worker health. NSSGA says OSHA’s proposal is important to its members because a silica standard would directly affect ready-mix and asphalt concrete operations, many aggregate sales yards, and practically all members’ customers. OSHA's regulatory analysis also will have an impact on the silica rule for mining operations that MSHA plans to propose. MSHA intended to publish its proposal this month, however this target date has since changed, according to… Keep Reading
Incorporating a rail line into a quarry and transportation system
Missouri was a hotbed of rock formation several hundred million or a few billion years ago. Magma periodically flowed beneath and above the surface of the earth, cooling and hardening. Today, the southern part of the Show Me State contains vast tonnage of Precambrian granite and trap rock to show for its molten past. Trap Rock and Granite Quarries LLC’s reserves feature Missouri red granite and trap rock deposits. This year, the company will begin to tap the rich groundswell with a state-of-the-art quarry loadout operation. The plan Trap Rock and Granite Quarries owns 3,200 acres in southern Illinois and southeast Missouri, with more than 1,100 of those acres situated 85 miles south of St. Louis near Iron Mountain, Mo. The 1,100-acre parcel was purchased three years ago after geologists concluded it contains an estimated 1 billion tons of granite and trap rock. But just as enticing to the company was what lay adjacent to the property: a main line of the Union Pacific Railroad. Union Pacific has about 1,400… Keep Reading
Why 2014 is the year of the workers’ voice
MSHA has recently expressed concern about fatalities in the aggregates industry and about employees taking risks by not focusing on potential consequences. The agency has emphasized that fundamental procedures, such as locking out and blocking equipment, are indispensable to preventing fatal releases of energy. It has further stressed the importance of operator reinforcement of safe procedures with regular training and monitoring of how miners are doing their work. There also appears to be tacit recognition that sometimes employees are not the best judge of their own competence on new assignments. MSHA is encouraging operators to provide and verify task training anytime there is a question. With that said, MSHA is also urging miners to insist on safe workplaces, and is emphasizing what miners can do to identify, correct and report unsafe conditions or actions. MSHA believes uninhibited communications between employees and companies can promote beneficial safety adjustments. MSHA stresses that miners who exercise safety rights, lodge complaints, talk to inspectors, or refuse work they consider unsafe are legally protected from… Keep Reading
6 steps to streamline mobile processing
Six simple solutions to enhance culture, improve safety and increase profits. Have you ever found yourself waiting impatiently at a traffic light when there were clearly no cars coming in the other direction?

Tips and technologies for hydraulic breaking
Following these tips and technologies for hydraulic breaking can save producers money and downtime. About as long as man has known rock, people have been designing and perfecting tools to demolish it. In recent years, hydraulic breaker technologies have evolved rapidly to include advancements that not only optimize breaking efficiency and reduce operating costs in mining and aggregate applications, but they help minimize downtime on the job. While performance of a breaker has traditionally been measured by the tons of rock per hour, says Stephane Giroudon, strategic account sales manager for Doosan, a breaker’s cost per ton is quickly becoming the industry standard. One of the easiest ways to keep your tool’s cost-per-ton ratio low is to identify technologies that help reduce the effects of the constant beating breakers take in the high-psi conditions associated with mines and quarries. Additionally, there are best practices that can contribute to the extended life of your attachment and your excavator. High-impact technologies The power and versatility of high-impact breakers allow operators to perform… Keep Reading
