This paper presents a novel method for developing the gateway tunnel without any excavation using directional tension blasting (DTB) in the mine by: 8.

    Abstract. Introduction of the state-of-the-art techniques in Mining operations, has been a never ending process and it has the ability to adopt technologies/methods available in other engineering and science disciplines keeping productivity, safety .   Information is also provided on blasting, slope stabilization, movement monitoring and civil engineering applications. This Fifth Edition has been extensively up-dated, with new chapters on weathered rock, including shear strength in relation to weathering grades, and seismic design of rock slopes for pseudo-static stability and Newmark.

      Zong-Xian Zhang, in Rock Fracture and Blasting, Introduction. Conventional drifting or tunneling by drilling and blasting method requires a much higher specific charge than ordinary production blasting such as bench blasting. For example, the specific charge at tunneling is 3–10 times higher than at bench blasting, depending on . Civil engineers could do a number of things at mining sites. Some of the tasks involved include helping to plan, design and oversee construction of buildings and structures, such as mining shafts. Engineers also need to use their skills to analyze survey reports, maps, blueprints and other topological or geologic data.

Blasting Technology has been written to meet the requirements of civil and mining engineers who need a comprehensive text on commercial explosives which also encompasses the practical and safety techniques employed when blasting is undertaken.

The book covers every aspect of blasting technology, including environmental control, surface and underwater excavation, underground coal and metal mining, and blasting Format: Paperback. About the Author. Sandro was born in Switzerland in He has a Master degree in computer science and a PhD in data mining from the Ecole Polytechnique Fédérale de Lausanne (EPFL).

His interests include data mining, data analysis, statistics, decision support, behavioral targeting and search engine optimization (SEO). Rock Mechanics and Its Applications in Civil, Mining, and Petroleum Engineering.

Abstract. Proceedings of the Geo-Shanghai International Conference, held in Shanghai, China, MayGSP contains 24 technical papers which cover recent advances in rock mechanics and its applications.

The excavation of rocks in mining and civil engineering applications by blasting technique is the most common technique since chemical blasting agents developed for centuries.

Dynamite is generally used in underground excavations as it produces less harmful gases during explosion. MINING INDUSTRY - Directional wells are used to produce methane gas that is contained in coal seams. - Methane presents a safety hazard and must be drained off before mining operations can begin.

- In deep coal seams that are beyond the reach of conventional mining techniques, directional wells can be drilled for in situ gasification projects.

Drilling and blasting is the traditional method of shaft excavation. This is labor intensive and time consuming. With the advent of machine boring, the RBM, or. The Programme in Blasting Engineering covers the basics of commercial explosives and the advanced application in both underground and surface mining environments.

You will also be introduced to the impact of fragmentation on the mining cycle, specialised blasting practices and the effect of blasting on the environment in more Size: 1MB.

The directional expansion of crack is satisfactory from the experiment and the result of field test is very good, the ruggedness fracture plane is less than 55 mm and the rate of half-hole marks. Civil Engineering July OVERVIEW When rock blasting is required for construction projects, the technique has a critical infl uence on overall project progress and costs.

Lack of understanding of the discipline leads to unfortunate outcomes, either through excessive constraints on the operation, or else the adoption of cheap, inappropriateFile Size: KB. Under the conditions of high ground stress and mining disturbance, the strata breakage that is induced by mining is severe.

Thus, it is critical to investigate the structural characteristics of key strata (KS) in deep thick mining. This study introduces an innovative technology, namely, directional blasting fracturing, in which an energy-gathering tube is installed in a borehole.

Methods of Application Methods of applying abrasive materials can be segregated into two distinct types of procedures: dry and wet. Dry-blasting: There are two methods used for dry-blast cleaning; mechanical blasting and air pressure blasting Mechanical Blasting: Mechanical blasting most frequently employs Rock breakage with explosives has existed since the seventeenth century when black powder came into use in mining.

Since then it has progressed from the invention of dynamite to the use of heavy ANFO. During the past two decades, there have been numerous technical contributions which have brought a better understanding of rock fragmentation with explosives, an 5/5(1).
