America: Prof. Dr. Gang Chen, Department of Mining and Geological Engineering, University of Alaska Fairbanks，P.O. Box 755900 Fairbanks, AK 99775-5900, USA, E-mail: ffgc@uaf.edu. Manuscripts will be reviewed by a minimum of two referees and will be considered for publication on the basis of originality of contribution. Manuscripts should be submitted in English.

Submission of a paper implies that it has not been published previously, that it is not under consideration for publication elsewhere, and that if accepted it will not be published elsewhere in the same form, in English or in any other language, without the written consent of the publisher. Only those papers that have not been submitted or published elsewhere, wholly or part, can be considered for publication. Authors must inform the editor if their manuscript has been submitted, and rejected, by another journal.

 

Manuscript Preparation
General: Manuscripts must be typewritten, double-spaced with wide margins on one side of white paper. Good quality printouts with a font size of 12 or 10 pt are required. The corresponding author should be identified (include a fax number and e-mail address). Full postal addresses must be given for all co-authors. An electronic copy of the paper should accompany the final revised version.

Abstracts: Each manuscript should be accompanied by an abstract of up to 100 words.

Text: Follow this order when typing manuscripts: Title, Authors, Affiliations, Abstract, Key words, Main text, Acknowledgements, Appendix, References, Figure Captions and then Tables. Do not import the Figures or Tables into your text. The corresponding author should be identified with an asterisk and footnote, which should contain this author's e-mail address. All other footnotes (except for table footnotes) should be identified with superscript Arabic numbers.

References: All publications cited in the text should be presented in a list of references following the text of the manuscript. The list of references should be arranged alphabetically by authors' names. References should be given in the following form:
