A Handbook for the Use of Engineers and others Engaged in Mining, Tunnelling, Quarrying, &c.

BY OSCAR GUTTMANN, Assoc. M. INST. C.E. Member of the Societies of Civil Engineers and Architects of Vienna and Budapest, Corresponding Member of the Imp. Roy, Geological Institution of Austria, &c.

** Mr. GUTTMANN'S Blasting is the ONLY work on the subject which gives at once full information as to the NEW METHODS adopted since the introduction of Dynamite, and, at the same time, the results of MANY YEARS PRACTICAL EXPERIENCE both in Mining Work and in the Manufacture of Explosives. It therefore presents in concise form all that has been proved good in the various methods of procedure. The Illustrations form a special and valuable feature of the work.

GENERAL CONTENTS.-Historical Sketch-Blasting Materials-Blasting Powder-Various Powder-mixtures-Gun-cotton-Nitro-glycerine and DynamiteOther Nitro-compounds-Sprengel's Liquid (acid) Explosives-Other Means of Blasting Qualities, Dangers, and Handling of Explosives-Choice of Blasting Materials-Apparatus for Measuring Force-Blasting in Fiery Mines-Means of Igniting Charges-Preparation of Blasts-Bore-holes-Machine-drilling-Chamber Mines Charging of Bore-holes-Determination of the Charge-Blasting in Boreoles-Firing-Straw and Fuze Firing-Electrical Firing-Substitutes for Electrical Firing-Results of Working-Various Blasting Operations-Quarrying-Blasting Masonry, Iron and Wooden Structures-Blasting in earth, under water, of ice, &c.

"The details of colliery work have been fully described, on the ground that collieries are more often made REMUNERATIVE by PERFECTION IN SMALL MATTERS than by bold strokes of engineering. It frequently happens, in particular localities, that the adoption of a combination of small improvements, any of which viewed separately may be of apparently little value, turns an unprofitable concern into a paying one."-Extract from Author's Preface.
