Methods and Results of Strip-Mine Reclamation in Germany1
No. 2 GEOLOGY OF COAL OVERBURDEN 75 METHODS AND RESULTS OF STRIP-MINE RECLAMATION IN GERMANY1 WILHELM KNABE2 Federal Research Organization for Forestry and Forest Products, Reinbek Hamburg, Germany All over the world industry is growing rapidly. This growth includes a great increase of surface mining or strip mining, as you call it. In the last 20 years, it has increased much more than underground mining, which, in some of the old industrial countries, is decreasing substantially. A number of factors have con- tributed to this trend; these include the development of heavy equipment, lower costs, more complete recovery of the coal, and smaller labor requirements. The American strip mines for bituminous coal and the German opencast mines for brown coal (also called lignite) are among the most important examples. This report will present the facts and trends of mining and reclamation in Germany only; it will not at this time make any direct comparison with the situation in Ohio. As you will see, there are very different conditions and solutions, but also very similar trends and problems in the two countries. Let me take three examples. (1) In both countries the mining industry is forced to go deeper and deeper into the earth, because many of the most favor- 1Presented at the Strip-mine Symposium held at the Ohio Agricultural Experiment Station on August 13-14, 1962. 2Summer 1962: Post-Doctoral Fellow, Ohio Agricultural Experiment Station, Wooster, Ohio.

Engineering Geology Field Manual
Chapter 19 BLAST DESIGN Introduction This chapter is an introduction to blasting techniques based primarily on the Explosives and Blasting Procedures Manual (Dick et al., 1987) and the Blaster’s Handbook (E.I. du Pont de Nemours & Co., Inc., 1978). Blast design is not a precise science. Because of widely varying properties of rock, geologic structure, and explo- sives, design of a blasting program requires field testing. Tradeoffs frequently must be made when designing the best blast for a given geologic situation. This chapter provides the fundamental concepts of blast design. These concepts are useful as a first approximation for blast design and also in troubleshooting the cause of a bad blast. Field testing is the best tool to refine individual blast designs. Throughout the blast design process, two overriding prin- ciples must be kept in mind: (1) Explosives function best when there is a free face approximately parallel to the explosive column at the time of detonation. (2) There must be adequate space for the broken rock to move and expand. Excessive confinement of explosives is the leading cause of poor blasting results such as backbreak, ground vibrations, airblast, unbroken toe, flyrock, and poor fragmentation. Properties and Geology of the Rock Mass The rock mass properties are the single most critical variable affecting the design and results of a blast. The FIELD MANUAL rock properties are very qualitative and cannot be suffi- ciently quantified numerically when applied to blast design. Rock properties often vary greatly from one end of a construction job to another. Explosive selection, blast design, and delay pattern must consider the specific rock mass being blasted. -
