Abstract

The use of explosives is an efficient and economically viable way for blasting rock in mining. However, it is know that 20-30% of the energy of explosives is actually used in rock fragmentation and the rest of this energy ends up causing impacts on the environment such as noise, vibration, gases, dust and flyrocks. Thus, there is a real risk to structures and people around of quarries and mines in general when there is no concern about blasting planning. This work seeks, through the blasting rock monitoring, to measure and predict the acoustic pressure or noise in the region called Caieiras in Caçapava do Sul, since previous works presented results which exceeded the limits prescribed by NRM-16 and NBR-9653/2005. Monitorings were performed and alternatives were tested in order to decrease the noise levels like covering detonating cords with sandy-clay materials, using lighter detonating cords, or even replacing them by shock tubes.

Ethical guidelines for journal publication

The REMOA is committed to ensuring ethics in publication and quality of articles. 
Conformance to standards of ethical behavior is therefore expected of all parties involved: Authors, Editors, Reviewers, and the Publisher.

In particular, 

Authors: Authors should present an objective discussion of the significance of research work as well as sufficient detail and references to permit others to replicate the experiments. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable. Review articles should also be objective, comprehensive, and accurate accounts of the state of the art. The authors should ensure that their work is entirely original works, and if the work and/or words of others have been used, this has been appropriately acknowledged. Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable. Authors should not submit articles describing essentially the same research to more than one journal. The corresponding author should ensure that there is a full consensus of all co-authors in approving the final version of the paper and its submission for publication.

Editors: Editors should evaluate manuscripts exclusively on the basis of their academic merit. An editor must not use unpublished information in the editor's own research without the express written consent of the author. Editors should take reasonable responsive measures when ethical complaints have been presented concerning a submitted manuscript or published paper.

Reviewers: Any manuscripts received for review must be treated as confidential documents. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviews should be conducted objectively, and observations should be formulated clearly with supporting arguments, so that authors can use them for improving the paper. Any selected referee who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the editor and excuse himself from the review process. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.
