Shafts have critical importance in deep mines and underground constructions. There are several traditional and mechanized methods for shaft sinking operations. Using mechanized excavation technique is an applicable alternative to improve project performance, although impose a huge capital cost. There are a number of key parameters for this selection which often are in conflict with each other and decision maker should seek a balance between these parameters. There- fore, shaft sinking method selection is a multi criteria decision making problem. This paper intends to use the combination of analytical hierarchy process and TOPSIS (Technique for Order Performance by Similarity to Ideal Solution) methods under fuzzy environment in order to select a proper shaft sinking method. A real world application is conducted to illus- trate the utilization of the model for the shaft sinking problem in Parvadeh Coal Mine. The results show that using raise boring machine is selected as the most appropriate shaft sinking method for this mine.

  • I Sub: - Underground Coal Mining Chapter – Shaft Sinking
    NARAYANI INSTITUTE OF ENGINEERING & TECHNOLOGY ARAHAT, ANGUL 4th Semester, Mining Engineering Theory – I Sub: - Underground Coal Mining Chapter – Shaft Sinking Definition Shaft: A vertical or inclined opening from surface for the conveyance of men, materials, hoisting ore, pumping water and providing ventilation. Sinking: The work in excavating a shaft. SHAFT SINKING It may be described as an excavation of vertical or inclined opening from surface for conveyance of men, materials, ventilation, pumping water, in addition to hoisting ore and waste rock. It is also called Shaft Construction or Shaft Mining. AIM OF THE PROJECT To study conventional and advanced techniques of shaft sinking. To increase the production and productivity in method of working adopted to win the ore or mineral deposit by selecting appropriate and suitable available technologies for shaft sinking in Indian mines. OBJECTIVE OF PROJECT . Increasing the safety during sinking. The conditions inside the mine is needed to be improved . The safe transport of the waste/ material/men. Increasing the production, efficiency and productivity of underground mine. To improve the ventilation arrangement of a mine. For this we require the construction of a new, sufficiently dimensioned shaft. PURPOSE OF SHAFT SINKING: - Shaft sinking is used for many purposes. To transport men and materials to and from underground Workings. For hoisting ore and waste from underground. To serve as intake and return airways for the mine (ventilation shaft). To access an ore body These shafts are used in applications such as hydro electric projects, water supply, waste water shafts and tunnel projects. Drilled shaft machine is used in such process, where it consists of special type of units that are used in both stable and unstable soils.

  • Tunnels, Shaft and Development Headings Blast Design
    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 and tunnels are used to build spillways around dams, and penstocks for water feed to underground power plants. Large tunnels are also used to build underground rail and roadways. Design principles for shaft, tunnel, and raise rounds are reviewed and demonstrated in this section. Hanging Lake Tunnels on Interstate 70, Glenwood Springs, CO REVEY Associates, Inc. 2005 Page 1 Underground Blasting Technology ______________________________________________________________ DEFINING REQUIREMENTS AND CONDITIONS In an ideal situation, designers would have unlimited choices regarding explosives selection, and drilling equipment. However in most situations, blast designers do not have complete control over all of the variables affecting blast design. Round dimensions are usually pre-set, and designers must often accept the limitations that come with using existing drilling equipment drilling equipment. Despite some limitations, many other design elements can be adjusted to improve round design. Drill patterns and explosive loads can be modified, and within drilling equipment limits, hole-size can be changed. Following, is a list of typical considerations that designers should define when they develop new, or attempt improvement to existing, heading rounds. HEADING ROUND DESIGN CONSIDERATIONS 1. Heading production goals; advance rates, and schedule. 2. Ground conditions; rock strength and structure. 3. Shaft or tunnel excavation dimensions. 4. Overbreak limitations, and perimeter loading specifications. 5. Vibration and airblast limits.
