It covers a theoretical background of the rock blasting technology and comprehensive case studies on different stages of rock blasting for underground metalliferous mining. It includes the discussions on burn-cut face blasting pattern, slot raise excavation methodology, and ring blasting methods. It further discusses different practical challenges associated with underground blasting, viz. ore dilution, ground vibration, wall instability, etc., and their possible solutions. The book also covers the recent advancements in methodologies to predict blasting outcomes and instrumentations for monitoring rock blasting operations. The book is a useful reference for rock blasting practitioners, mining engineers, professionals, and researchers. It is also a valuable reference for undergraduate and postgraduate students. 001468435 650_0 $$aBlasting. 001468435 650_0 $$aHard rock mines and mining. 001468435 655_0 $$aElectronic books. 001468435 77608 $$iPrint version: $$z9819926440$$z9789819926442$$w(OCoLC)1375058505 001468435 852__ $$bebk 001468435 85640 $$3Springer Nature$$uhttps://univsouthin.idm.oclc.org/login?url=https://link.springer.com/10.1007/978-981-99-2645-9$$zOnline Access$$91397441.1 001468435 909CO $$ooai:library.usi.edu:1468435$$pGLOBAL_SET 001468435 980__ $$aBIB 001468435 980__ $$aEBOOK 001468435 982__ $$aEbook 001468435 983__ $$aOnline 001468435 994__ $$a92$$bISE
