TUNNELS, SHAFT AND DEVELOPMENT HEADINGS
BLAST DESIGN INTRODUCTION Tunnels, shafts, and raises are developed for a variety of purposes In mines development headings provide; mine access for men and materials, ore and waste hoisting, and ventilation paths Shafts are also used in civil construction projects In hydroelectric projects, shafts andas blast design, site geology and receiving structure, the blast vibration levels can be predicted 610 Fauld Mine is a ‘room and pillar’ gypsum/anhydrite mine The material is mined using the drill and blast technique due to the hardness of the mineral deposit Blasts in aFauld Mine – Southern Extension NonTechnical Summary
A Visitors Guide to Brightling Mine
During the 1890’s, the gypsum mine's workforce gradually rose from 15 to 27 men underground and from 22 to 60 on the surface and the business amalgamated in 1903 with the Kingston Gypsum Company of Nottingham to form the Gypsum Mines Limited The new companyBender (1999) defined production blasting as the type of blasting that is designed to fragment a predetermined volume of rock; widely spaced holes are drilled and fired in a controlled delay sequence(PDF) ROCK BLASTING FOR MINING ResearchGate

Investigation of Instability and Blasting Caving
According to the structure form of room and pillar goaf in gypsum mine, the mechanical model of pillar roof composite supporting structure was established in this research Based on the cusp catastrophe theory and energy dissipation theory, the energy dissipation relationship of the support structure was analyzed, and a new instability criterion of the support1 Introduction Mining activity is mostly represented by these four main operations: drilling, blasting, loading and hauling For a proper mine planning and design, all of these operations need to be carefully planned in such a manner that can prevent extra loads such as operating costs, environmental footprints, etc Amongst these operations, drilling and blastingOptimized design of drilling and blasting operations in
