Rock fragmentation and optimization of drilling tools
In this chapter possibilities of the improvement of drilling tool efficiency on the basis of the analysis of mechanisms of rock destruction and some methods of the information theory are considered. Physical mechanisms of destruction of hard and plastic rocks under different conditions of mechanical loading are reviewed. Some physical effects which allow to improve the efficiency of rock drilli...
متن کاملDrilling Cost per Unit Volume of Removed Rock - a Criterium of Optimization of Drilling
An approach to the optimization of drilling tools which is based on the analysis of dependence of drilling cost on the tool shape is presented. The effect of tool shape on the energy consumption in rotatory drilling and on the lifetime of tool is studied analytically. It is shown that the main part of drilling energy is consumed not for the rock removal, but rather by the microfracture, shearin...
متن کاملWaterjet Assisted Polycrystalline Diamond Indentation Drilling of Rock
The use of high-pressure waterjets as a method for enhancing the performance of mechanical cutting tools has been well documented over the years. However, concurrent with this development for drag bit tools, there has been some evidence that the combination was not an effective one. By using sectioned samples of rock indented with a spherical indentor (of the type used in percussive drilling) t...
متن کاملLaser Rock Drilling by A Super-Pulsed CO2 Laser Beam
High power carbon dioxide lasers have successfully been used in drilling or cutting ngineering materials such as metals, polymers and ceramics over the years. Can a arbon dioxide laser be used to efficiently drill different rocks in a deep gas well? esearch sponsored by US Department of Energy has been carried out to answer this uestion. This paper will report the study results of using a super...
متن کاملPerformance analysis of drilling machines using rock modulus ratio
Rotary drills, diamond drills and percussive drills have been extensively used in open pits, quarries and construction sites. The prediction of the penetration rate of drilling machines is very important in the cost estimation and the planning of the rock excavation projects. The rock modulus ratio, which is the ratio of elastic modulus to compressive strength, indicating the deformability, is ...
