6/1/2008 - Conference papersThe paper provides: (a) a description of the gas pressure-based design approach to blasting, (b) a simple technique for estimating the damage radius of the buffer row of holes, and (c) a discussion of smoothwall design for the contour row of holes.
-
2/1/2005 - Conference papersThis paper examines the factors related to injuries due to inadequate blasting shelters and blast area security, and identifies mitigation techniques.
-
2/1/2005 - Conference papersDescribes a small-scale field study to identify key factors that may contribute to the migration of CO through the ground.
-
8/1/2000 - Conference papersRock drilling parameters including thrust, rotational speed, torque and velocity were examined to determine the ability to identify the strength of the rocks being drilled from the measured parameters.
-
7/1/2010 - Conference papersInstrumented test sites were installed in the tailgates of two western longwall operations; results of the support performance and ground reaction are presented in terms of developed support loads and displacements and tailgate entry convergence.
-
3/1/2010 - Conference papersThe authors' goal is to summarize the totality of the USBM's explosives and blasting research.
-
6/1/2008 - Conference papersThis paper presents the results of a NIOSH parametric study that quantifies the impact of various deformable materials in block stopping construction under transverse load conditions.
-
1/1/2008 - Conference papersNIOSH researchers collected basic data from two blast rounds at the SSX-Steer Mine as a component of a larger study on controlled blasting, the goal of which is to reduce injuries from falling rocks in underground mines.
-
1/1/2008 - Conference papersThis paper presents a modification which corrects the mathematical error in the Holmberg-Persson approach to perimeter blast design.
-
7/1/2007 - Conference papersAn intelligent drilling system has been developed that can complement scoping and core analysis to provide a more complete picture of roof strata and is capable of seeing features or conditions that are not always obvious in more traditional methods.
