DESCRIPTION - summary of the module content
AIMS - intentions of the module
This course provides further study of the commercial use of explosives, an overview of mine development techniques, and the study of mine drainage. This course introduces the student to the selection of underground mining methods and their associated extraction systems. The course further provides a major practical surface surveying exercise which is held over three weeks after the first year June exams at the Tremough Campus. The course also provides for 1 week of practical underground surveying undertaken during Activities week in the first semester at the CSM Test Mine field station.

SYLLABUS PLAN - summary of the structure and academic content of the module
Weeks 1-2 Explosives Engineering - The explosion process, general principles of the dynamic effects of blasting and rock fracture. Optimum design of simple blasts for tunnelling, stoping and quarrying; fragmentation; design of multi-row blasts, influence of delayed detonation and rock structure; mechanics of rock breaking with inclined and vertical holes, operational problems; pre-splitting and smooth-wall blasting. Environmental problems; flyrock, air-blast and ground vibration. Weeks 3-4 Shaft Sinking and Development - Factors determining shaft selection and location. Collar designs, high speed sinking of vertical shafts, lining and equipping. Conventional and boring methods. Shaft deepening. Rock hoisting methods. Hoisting regulations. Development techniques for raising. Raiseboring. Weeks 5-6 Mine Drainage - Inflow control. Active and passive dewatering methods and removal of mine water. Design and siting considerations for pumping stations, sumps, settlers and sludge pumping. Precautions in proximity to aquifers, mine and other workings including provisions of Mines and Quarries legislation. Flood control, watertight doors. Weeks 7-8 Underground Rock Handling - Gravitational systems, characteristics of orepasses, Operational characteristics of scrapers, rockershovels, load-haul-dump equipment, influence on development design and mining techniques, future trends. Main haulage systems. Week 9 Underground Extraction Systems - Stoping: classification of methods; the influence of geological factors, virgin and induced stress fields and rates of extraction. Development ratios, recovery and dilution. Selection of methods; open, filled and caving systems, pillar recovery. Optimisation of extraction and mining efficiencies. Case examples. Surface Survey Course : Layout of networks. Precise theodolite traverse. Use of theodolite, EDM and total stations along with DGPS. Standards of accuracy required. Calculations for station coordinates. Selection of instrumentation. Selection of survey stations. Computations for bearing, coordinates and elevations with closing errors and adjustments. Levelling. Station elevations determined by a range of instrumentation and techniques to precise and subsidiary survey standards. Calculation of reduced levels and distribution of closing error. Detail survey by total station, offsetting and radial pickup.. Underground Survey Course: Connection to underground grid from control stations on surface. Underground control network surveying using wall stations along with 3D detail pick up. Both courses : Preparation of group(5 students) written survey report including computations and field records to meet client specification. Presentation of group (5 students) plan based on data input into LSS and onward to plan production using Auto Cad.
