7/1/2008 - Conference papersThis paper reviews 11 prevention control techniques for coal mine bursts.
-
7/1/2008 - Conference papersThis paper explores the relationships between deep-seated and shallow in situ stresses in several of the world’s coalfields, using a data base of more than 350 stress measurements from underground coal mines.

11/1/2007 - Technology NewsResearch by NIOSH on multiple-seam mining has resulted in two ground control products. The first is IC 9495 which is a proceedings document. The second is the Analysis of Multiple-Seam Stability software package. Each product is briefly described.
-
7/1/2007 - Conference papersThis paper describes some successful techniques and machine modifications that were evaluated for ergonomic considerations and are being used in productive mines to assist with roof screen installation.

10/1/2006 - Conference papersHand scaling is a physically demanding job responsible for overexertion injuries in mining. This experiment studied rib scaling from an elevated bucket to examine force generation capabilities and electromyographic responses to a prying subtask.
-
8/1/2006 - Conference papersBowie Resources maintains one of the most pro-active ground control programs in the U.S. mining industry today. Everyone in the organization from the miners to top management is involved in ground control. The program is described in detail.
