Blasting in ground excavations and mines / Взрывные работы в подземных выработках и шахтах

In the present economic scenario of our country, the mining industry in India requires some economic ami innovative approaches for enhanced coal and mineral production. With the increased development of open pit mines for base minerals and particularly (he extensive demand of coal, (he practicing mining engineers arc finding that they have problems in new technology and new ideas which arc particularly associated with mine and ground excavations. Some of (hem arc in common with those traditionally associated with civil engineering. The civil engineers, on the other hand, are producing ever large surface and subsurface excavations and arc finding that they have much to gain from the problems and solution of mining rock mechanics. In this juncture, rock blasting techniques and ils fruitful utilisation for optimum production, has undoubtedly a very important and significant role. <...>
