O-Pitblast on the leading edge of blasting softwares

O-Pitblast prides itself on creating enthusiasm and enjoyment whenever we present our products to new people. This time it was Eng. Hugo Herrera Solis from Blasting Engineering LA. We had a wonderful meeting with him!

Why is O-Pitblast so well received by our costumers? It’s easy: user friendly interface with a quick learning curve, always updated to keep up the mining market and it’s composed by a young team that strives to be the bleeding edge of blasting softwares.

O-Pitblast sharing their scientific findings at ISEE 2019

In January, at the International Society of Explosives Engineers, Francisco Leite and Raquel Sobral stepped to the stage to present O-Pitblast latest scientific research findings.

Francisco Leite presenting the new O-Pitblast article: “Borehole Deviation Control Using Electronics: An Eulers Approach”.

“(…) The authors decided to evaluate the possibility of measuring hole deviation by creating a portable prototype using an electronic sensor capable of measuring the acceleration on objects, that is, to measure the own acceleration of a system, known as “accelerometer” and a micro-controller to handle and treat data “The main idea behind this paper is to validate the power of the Euler method, given the stepping limitations of the sensor and micro controller in order to reproduce of the hole shape. A case study was carried out, comparing the measurements of borehole deviations made by a traditional equipment and the prototype .

Raquel Sobral doing the introduction to the article “Blast Pattern Expansion – A heuristic Approach”.

“Reviewing some recent articles leads us to an enriching experience, since the authors of these articles clearly model the problem, but do not address the mathematical solution of these models, which in turn, given their non-linear nature, have no directly and easy solution. Simple and even robust optimizers present in the market show different results and often do not converge to a single solution. To address this problem, an adapted gradient heuristic-based model was developed to try to find optimum values. Heuristics search for values of stemming, subdrilling, burden and spacing that minimize the costs of blasting and drilling. This search, which by the nature of the heuristic moves the solution in the direction of the gradient with maximum decrease to find optimal solution, found values that in turn, when compared with values presented by market solutions not only equaled them as, in some situations, even improved the proposed solution.”

O-Pitblast at ISEE 2019, Nashville

Last month, O-Pitblast team was present at the International Society of Explosive Engineers in Nashville. We want to thank the entire organization for this great event. Congratulations!

“The International Society of Explosives Engineers aims to promote the professional development, competence, and qualifications of explosives engineers, practitioners and those entering the field; to serve society as a body of specialists and encourage service to the community where the skills of those who work with explosives can best be applied; to promote a favourable public perception of explosives engineers and the contributions that they make to society (…)”
