6/1/2008 - Conference papersIn this investigative study NIOSH measured for sub-micrometer elemental carbon (EC) using two types of control technologies (ventilation and cabs) which are being implemented in limestone mines.
-
6/1/2008 - Conference papersThis study proposes a principle component analysis (PCA) and artificial neural network (ANN) approach to predict the ventilation methane emission rates of U.S. longwall mines and the optimum combination of degasification boreholes based on the given cha...
-
2/1/2008 - Conference papersThis NIOSH study presents an approach for prediction of methane inflow rates using coalbed methane reservoir modeling which can be used to limit the methane concentrations occurring as a result of the influences of various coalbed and operational parame...
-
2/1/2008 - Conference papersThis paper describes NIOSH research demonstrating that the ventilation of large-opening mines improves significantly by including ventilation requirements in the mine planning process and implementing some practical techniques during mining.
-
2/1/2007 - Conference papersThe fact that methane ignitions continue to occur at the mining face indicates that monitoring with machine-mounted methanometers does not always indicate the presence of high methane concentrations. Methane concentrations at the face change quickly du...

2/1/2007 - Conference papersDuring the 20th century, the increased emphasis on worker health and safety and the advent of new mining equipment and methods led to many changes in mine face ventilation practices.

6/1/2006 - Conference papersA cooperative research effort was established to lower respirable dust levels in an iron ore grinding and concentrator plant. The most significant improvement was realized by changing the ventilation profile throughout the entire facility. Another succe...

6/1/2006 - Conference papersThe Super Stopping is designed as a long-term permanent stopping for use in the main entries of the mine, while the EZ-Up Curtain Stopping, although very durable, is designed more for portability and ease of installation. This paper describes the design...

6/1/2006 - Conference papersA new protocol based on rigid arch loading of the structure is proposed to determine the true transverse load capacity of block stoppings. Tests show that load capability depends on the block's physical properties and the wall's geometric properties.
-
6/1/2006 - Conference papersTests were conducted in a full-scale ventilation gallery with a model mining machine that simulated airflow created by a dust scrubber. The results showed that operation of machine-mounted scrubbers improved face ventilation when blowing ventilation is ...
