“…They also found mineral particles to be more efficient for drilling than metal particles. Cui et al (2011) performed material removal experiments on a set cementsilica-sand mixture with impinging steel balls, and they noted an increase in eroded volume with an increase in particle diameter. Momber (2013) investigated the response of schist to solid particle erosion and found notable features of plastic deformation.…”

Effects of fracture toughness on the impingement of geomaterials (rocks and cementitious composites) by quartz particles at velocities between 40 and 140 m/s are investigated experimentally and analytically. If schist is excluded, relative erosion (in g/g) reduces according to a reverse power function if fracture toughness increases. The power exponent depends on impingement velocity, and it varies between -0.64 and -1.33. Lateral cracking erosion models, developed for brittle materials, deliver too high values for relative material erosion. This discrepancy is partly attributed to stress rate effects. Effects of R-curve behavior seem to be marginal. An integral approach E R = K 1 Á E R P ? (1 -K 1 ) Á E R L is introduced, which considers erosion due to plastic deformation and lateral cracking. A transition functionsuggested in order to classify geomaterials according to their response against solid particle impingement.

“…In engineering practice and application of particle jet impact rock-breaking technology, Particle Drilling Technology Inc. (PDTI) of USA has carried out many laboratory tests and improved field tests, which show that particle jet impact drilling technology could achieve rapid drilling in hard formations [10]. e successful application of particle impact rock-breaking laboratory test and field experiment shows that the rock-breaking technology has broad application prospects in improving drilling speed [11][12][13][14]. In theoretical research of rock broken, many professors have studied the theory of rock breaking by high-pressure water jet and particle jet impingement [15][16][17][18][19][20].…”

Particle jet impact drilling technology is an efficient method which mainly uses high-velocity particles to break rock. As the important criterion for evaluating rock-breaking effect, rock-breaking depth and damage area were studied in this paper. Firstly, a particle jet impact rock-breaking test device was developed, and laboratory experiments have been carried out. Then, based on the spherical cavity expansion theory, the mathematical model of rock-breaking depth and damage area under particle jet impact was established. Afterward, the effect of water-jet impact velocity, impact angle, and particle diameter on rock-breaking depth and damage area was analyzed by comparing experimental results and mathematical calculation. The results show that rock-breaking depth and damage area would increase with increase of water-jet impact velocity and decrease slightly with increase of particle diameter. And the combination of 8° and 20° is recommended for nozzle layout. The experimental results and mathematical calculation are basically consistent, which could verify the correctness of the mathematical model. The study has significance for development and application of particle jet impact rock-breaking technology and perfection of theoretical research.

“…Despite these advantages, very little work has been reported about the use of numerical methods to the study the hydrodynamics of full PID systems. Among the few exceptions we find the works [19,28,49,35,68], all based on finite volume method, or the experimental work [67], that studied the rate of erosion of the substrate under different impact conditions.…”

A numerical technique based on a CFD-DEM method is presented for the analysis of particle impact drilling (PID) systems. The method is build from a preexisting finite element Navier-Stokes solver for the fluid phase and a discrete element method module for the steel particles which this drilling technology utilizes to enhance the penetration rate. We provide a detailed description of the most relevant implementation issues, including our choice of the hydrodynamic forces appropriate for power-law fluids. We also discuss several critical aspects related to the validity of the simplifying assumptions that will be helpful to simulation engineers. We apply our simple, one-way coupled approach on designs provided by an industrial partner to illustrate its potential as an analysis tool for this promising drilling technology.
