1/1/1999 - Conference papersThe process of drilling and bolting the roof is currently one of the most dangerous jobs in underground mining, resulting in about 1,000 accidents with injuries each year in the United States. To increase the safety of underground miners, researchers f...
1/1/1998 - Hazards IDsRecently, the National Institute for Occupational Safety and Health (NIOSH), through its Community Partners for Healthy Farming program in New York, received two separate reports of farm workers who were injured while attempting to drill holes into seal...
1/1/1997 - NIOSH/USBM numbered publicationsThis pamphlet provided information on what rock drillers can do to protect themselves from silica dust, which may cause silicosis. The role of exposure to silica dust in the development silicosis was discussed.
Technology News 447 - Dust Collector Discharge Shroud Reduces Dust Exposure to Drill Operators at Surface Coal Mines3/1/1995 - Technology NewsDust collector discharge shrouds were used to reduce airborne respirable dust generated from emptying dry dust collectors on small truck-mounted drills at surface coal mines.
1/1/1995 - Reports of InvestigationsDust control modifications were implemented on small, truck-mounted rock drills at surface coal mines. The control techniques showed noticeable improvement in measured dust concentrations around the drills.
10/1/1994 - Technology NewsA method is described to increase the dust-control effectiveness of the Rotoclone dry-dust collection systems used on surface coal mine drills.
1/1/1990 - Reports of InvestigationsThe Bureau of Mines preproduction wireless survey system (WSS) and its performance during an in-mine test are discussed in this report. The WSS was developed to reduce downhole surveying time in order to increase the efficiency of drilling long horizont...
1/1/1988 - Reports of InvestigationsThis Bureau of Mines report investigates the horizontal trajectory of boreholes drilled in coalbeds using the rotary drilling technique.
1/1/1987 - Information CircularsThis Bureau of Mines report describes in detail the design and operation of a test apparatus for measuring the sound power levels of drills used by the mining industry.
1/1/1985 - Reports of InvestigationsThis Bureau of Mines report describes and compares the procedures, capital investments, and operating costs of rotary and in-hole motor drilling techniques used to drain methane gas from the Pittsburgh coalbed in an underground mine located in southwest...
