{"product_id":"2940013212541","title":"Impact of Control Parameters on Shearer-Generated Dust Levels","description":"Previous research on continuous mining operations has shown that significant interactions exist between dust-control parameter application and the resulting respirable dust levels. However, simply increasing the level of the controls does not guarantee a reduction in respirable dust levels. Full-scale laboratory tests are being conducted to provide information to longwall operators that would assist them in selecting control parameters to reduce dust levels for mine-specific conditions. The interactions between face air velocity, shearer water quantity, drum water spray pressure, external water spray pressure and spray system design were evaluated in a simulated 2.13-m (7-ft) coal seam for two cutting directions. Locations around and downwind of the shearer were monitored to evaluate relative changes in respirable dust levels as a function of each control parameter.","brand":"1001 Property Solutions LLC","offers":[{"title":"Default Title","offer_id":47069891559664,"sku":"2940013212541","price":1.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940013212541_p0.jpg?v=1763589571","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940013212541","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
