Best Practices for Dust Control in Coal Mining

Compiled via the U. S. Dept of health and wellbeing and Human providers, CDC/NIOSH workplace of Mine security and overall healthiness learn, this 2010 instruction manual used to be built to spot to be had engineering controls that could support the decrease employee publicity to respirable coal and silica airborne dirt and dust. The controls mentioned during this instruction manual diversity from long-utilized controls that experience built into criteria to more recent controls which are nonetheless being optimized.

3. For caving methods, the available techniques are sublevel caving and block caving. 1. Due to the uniqueness of each ore deposit, the variations on each of these methods are nearly limitless. It is impossible to include even the major variations in this chapter; the goal of this chapter is to present the principles as a guide to the mining engineer in adapting the general methods to specific needs. The selection process described herein is intended to supply the techniques by which the candidate methods available for a given orebody can be reduced to one or two feasible approaches.

In narrow orebodies, parallel holes or holes in a fan-shaped pattern may be feasible and may be preferable to a ring pattern. Two principal drilling systems are used. 8 m (4 to 6 ft) sections. ). The hole length varies with the hole pattern, but Next Page 56 Choosing an Underground Mining Method normally does not exceed 24 m (80 ft). Longer holes are possible, but they may cause problems as a result of deflection from the intended direction. Recently, the application of down-the-holehammers has become common in sublevel stoping.

Certainly geostatistics does entail a relatively large amount of computation, involves somewhat “heavy“mathematical and statistical terminology, and generally requires the use of a computer. This, however, does not mean that the work need be done in isolation from the geologic staff. In fact, geologic cross sections, bench plans, and most important, the acquired understanding of the orebody by the geologic staff in terms of the lithologic, structural, or other controls on the mineralization, is of paramount importance in any geostatistical study.
