Additional Physical Format: Online version: Larson, William C. Airborne dust assessment at three metal mines and a silica mine.
[Washington]: U.S. Dept. of the Interior, Bureau of Mines, Assessment of respirable dust, personal exposures of miners and free silica contents in dust were undertaken to find out the associated risk of coal workers' pneumoconiosis in 9 coal mines of.
James G. Speight PhD, DSc, in Shale Oil Production Processes, Dust Emissions and Particulate Matter. The production of airborne dust particles is a major problem in underground mines, where dust explosions, with or without the release of gases, are the main concern. In addition, dust is not solely a localized problem since fine particles can be transported to contaminate areas far.
Oct 02, · These include Best Practices for Dust Control in Coal Mining, Best Practices for Dust Control in Metal/Nonmetal Mining, the second edition of the Dust Control Handbook for Industrial Minerals Mining and Processing, and Diesel Aerosols and Gases in Underground Mines: Guide to Exposure Assessment and Control.
The field assessment involved measurement of airborne respirable dust and respirable silica at all eight operating gold mines of the time. This article describes the details of the field assessment.
The first step of the evaluation, as directed in Figurewas the independent committee assessment of the major components of an ideal mining health and safety research tropheesrotary-d1760.com committee considered separately the health research and safety research needs of the mining industry.
Innovative concepts for Airborne dust assessment at three metal mines and a silica mine book airborne respirable silica dust generated in underground mining operations [Pittsburgh] In the mine all three categories can be used together (and should be viewed from a systems approach) to meet prevailing health standards.
Research Programs of the U.S. Bureau of Mines: First Assessment. Crystalline silica is a basic component of soil, sand, granite, and many other minerals.
Quartz is the most common form of crystalline silica. Cristobalite and tridymite are two other forms of crystalline silica. All three forms may become respirable size particles when workers chip, cut, drill, or.
Assessment of airborne dust generated from small truck-mounted rock drills. airborne respirable dust generated from emptying dry dust collectors on small truck-mounted drills used at surface coal mines.
Exposure to crystalline silica dust during rock drilling can cause respiratory disease. overexposure to respirable coal mine dust can Cited by: 3. The final rule extends the same medical surveillance requirements afforded underground miners, including chest x-ray examinations, to surface miners since they are also at risk of developing lung diseases and material impairment of health or functional capacity from exposure to respirable coal mine dust.
In addition, the final rule extends part. Rather than a focus on surface water discharges, remediation of the HMC site has a groundwater focus on multiple aquifers: i.e., the Alluvial, Chinle, and San Andres Aquifers.
The HMC site also has an airborne COC focus, with mine waste remediation requiring periodic mitigation of radon and airborne dust and water vapor exposures. Silicosis is a form of occupational lung disease caused by inhalation of crystalline silica dust.
It is marked by inflammation and scarring in the form of nodular lesions in the upper lobes of the tropheesrotary-d1760.com is a type of pneumoconiosis. Silicosis (particularly the acute form) is characterized by shortness of breath, cough, fever, and cyanosis (bluish skin).
It may often be misdiagnosed as Other names: Miner's phthisis, Grinder's asthma, Potter's. The prevailing view was that silicosis was very serious but it was solely caused by silica and not coal dust.
The miners' union, the United Mine Workers of America, realized that rapid mechanization meant drills that produced much more dust, but under John L.
Lewis they decided not to raise the black lung issue because it might impede the. Assessment of airborne dust generated from small truck-mounted rock drills "Recently the United States Bureau of Mines dust research program studied small surface mine drills to assess their dust generation hazards and the effect of dust control technologies implemented.
and mine worker exposure to silica dust continues to be an ongoing. () used historical data (n = ) and current measurements (n = ) to characterize exposure to respirable coal mine dust in three South African coal mines. Jobs were classified into the following exposure zones: face (directly involved with coal extraction), underground backbye (away from the coal mining face), and work on the surface.
A Computer-Controlled SEM-EDX Routine for Characterizing Respirable Coal Mine Dust. by G.T. Particle Size Distribution of Quartz and Other Respirable Dust Particles Collected at Metal Mines, Nonmetal Mines, and Processing S.J.
Identifying sources of respirable quartz and silica dust in underground coal mines in southern west Virginia Cited by: 6. Silica (silicon dioxide) occurs in crystalline and amorphous forms. Of the several crystalline polymorphs of silica found in nature, quartz is by far the most common, being abundant in most rock types, notably granites, sandstones, quartzites and in sands and soils.
Cristobalite and tridymite are found in volcanic rocks. Because of the wide usage of quartz-containing materials, workers may be.
Mar 13, · Respirable coal mine dust is a hazard in underground and surface coal mines and in coal-processing facilities. It is a mixed dust, consisting mostly of coal, but can also include silica, clay, limestone and other mineral dusts.
The composition of coal mine dust varies with the coal seam, the composition of the surrounding strata and mining methods. We have compiled three short case studies of environmentally-harmful mines, to illustrate the results on the environment and surrounding community of poorly regulated or monitored mines.
Greenland. Greenland Minerals and Energy Ltd, based out of Australia, planned. HEALTH AND SAFETY The Mines Regulations Made - - - - in relation to respirable crystalline silica, mg/m3 as a time-weighted average over a 40 “respirable dust” means airborne material which is capable of penetrating the gas exchange.
Asarco is subject to the jurisdiction of the Federal Mine Safety & Health Act and the Federal Mine Safety and Health Review Commission. Citation No. was based on one sample for airborne contaminants, which was taken over an eight-hour period on March 16, at the Young Mine. The citation issued by.
Airborne contaminants can present a significant threat to worker health and safety. Thus, identification and quantification of these contaminants through air monitoring is an essential component of a health and safety program at a hazardous waste site.
Reliable measurements of airborne contaminants are useful. EPA/X September SOURCE ASSESSMENT: OPEN MINING OF COAL State of the Art by S.

Martin Resource Extraction and Handling Division Industrial Environmental Research Laboratory. The Secretary must refer the recommendation to an advisory committee, or publish the recommendation as a proposed rule, or publish in the Federal Register the determination and reasons not to do so.
InNIOSH published and submitted to MSHA a Criteria Document on Occupational Exposure to Respirable Coal Mine Dust. May 21, · Many factors influence the health impact of exposure to metalliferous mine dusts and whilst the underpinning toxicology is pivotal, it is not the only driver of health outcomes following exposure.
The purpose of this review is twofold: (i) to highlight recent advances in our understanding of the hazard posed by metalliferous mine dust and (ii) to broaden an often narrowly framed health risk Cited by: 4. Astm d - D Dust Monitoring Services - Papers and publications pertaining to fallout or precipitating dust - ASTM This article outlines a practical method of establishing an environmental dust monitoring programme or even an in-depth investigation to establish sources of dust and quantify (Original text: quantifying the extent of the dust fall-out) the extent of dust fall-out.

May 26, · Silicosis is a fibrotic lung disease caused by inhalation of free crystalline silicon dioxide or silica. Occupational exposure to respirable crystalline silica dust particles occurs in many industries. Phagocytosis of crystalline silica in the lung causes lysosomal damage, activating the NALP3 inflammasome and triggering the inflammatory cascade with subsequent fibrosis.
