The Conference provides an excellent opportunity for sharing knowledge through presentations. The Conference plans to accept submittals for oral presentation and for poster presentation. Please refer to the schedule presented below for information relating to important dates for the submittal and review process.

An abstract of each presentation, either oral or poster, must be submitted for review and acceptance. Upon acceptance of an abstract, a full "draft" manuscript will be required. Upon review, a draft manuscript may be determined to require additional editing and/or modification before final publication; therefore, a final "camera ready" submittal may be required. Such editing may be performed by technical editors associated with the Conference, or the manuscript may be returned to the author(s) for incorporation of reviewer comments. If a draft manuscript is determined to be completely acceptable for publication, no final version will be required. Please note that full manuscripts are required for all presentations — oral or poster — made at the Conference.

In the case of poster presentations, the actual posters (the presentation materials posted at the Conference) will not be submitted for review or approval.

  • Rock - Very Hard and Abrasive rocks

Full Manuscripts

Full draft or final manuscripts shall be submitted as Microsoft Word (.doc, .docx) or Open Office Text (.odt) computer files. The manuscript within the file shall be "camera-ready"; that is, it shall be complete, properly formatted, and ready in all respects to be directly included in the collected Conference proceedings. Each full manuscript shall be constructed in strict accordance with defined instructions that are available for download from this website. Additional documents are also available for download: 1) an example of a properly formatted draft/final submittal as a Microsoft Word document (.doc), which can also be opened in Open Office Writer; and 2) an author's guide that provides information that may be useful in preparing the manuscript.

Oral and Keynote Presentations

Oral and Keynote presentations should be prepared to comply with duration requirements. Oral presentations should be no more than 20 minutes in duration, and Keynote presentations should be no more than 30 minutes in duration. Presenters should plan for a 3 to 5 minute question-and-answer period at the end of their presentation, which is included in the 20 or 30 minute target duration.

Oral and Keynote presentations are typically accompanied by visuals prepared with tools such as Microsoft PowerPoint. Such visuals are not required to comply with any defined template, design, or structure, and no template for their construction will be supplied by the Conference. Equipment at the Conference will display visuals in either 16:9 (widescreen) or 4:3 format. Visuals in 16:9 format will fill the screen vertically and horizontally; those in 4:3 format will fill the screen vertically but not horizontally, thus preserving the correct "look" of the visual.

Submittal of Documents

All abstracts and manuscripts shall be submitted to the Conference staff through a web-based Document Management System (DMS) whose address is:

Persons wanting to submit documents for the Conference should visit the website listed above and create an account. Those who create an account for use in submitting an abstract should use that account's credentials to access the DMS for subsequent submittals. Do not create more than one account on the DMS; a submitter must use the same DMS account for all submittals.

While it is not required that the person submitting documents is an author of a paper, all communication from the Conference staff concerning a paper will be directed to the person who submits the documents (the account holder). If the submitter/account holder is not also an author, it is the responsibility of the submitter to forward correspondence from the DMS to at least one author of the document(s).

For questions about document submission or for help with the Document Management System, please contact the Conference staff using the contact information available here.

Attendance of Conference

At least one author of each accepted presentation must register for and attend the Conference and must present the paper at the Conference in accordance with the applicable presentation schedule.
