煤和瓦斯突出的突发性和暴力性继续对中国煤矿安全构成严重威胁。关键问题之一是预测爆发的发生。中国目前用于预测爆发的方法被认为在某些煤层条件下是不充分的、不适当的或不切实际的。近年来，中国淮南矿业集团公司（淮南）和澳大利亚联邦科学与工业研究组织（CSIRO）共同开发了基于煤层含气量预测淮南突出发生的技术。在技术开发方面取得了重大进展，包括开发了更快速、更准确的煤层瓦斯含量测定系统，发明了随钻取样装置，用于快速和定点取样，以及将DEM和LBM代码耦合在一起，用于先进的突出起爆和扩展数值模拟。本文介绍了这些研究进展。(C) 2014年Elsevier B.V.代表中国矿业大学出版。
The sudden and violent nature of coal and gas outbursts continues to pose a serious threat to coal mine safety in China. One of the key issues is to predict the occurrence of outbursts. Current methods that are used for predicting the outbursts in China are considered to be inadequate, inappropriate or impractical in some seam conditions. In recent years, Huainan Mining Industry Group (Huainan) in China and the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia have been jointly developing technology based on gas content in coal seams to predict the occurrence of outbursts in Huainan. Significant progresses in the technology development have been made, including the development of a more rapid and accurate system in determining gas content in coal seams, the invention of a sampling-while-drilling unit for fast and pointed coal sampling, and the coupling of DEM and LBM codes for advanced numerical simulation of outburst initiation and propagation. These advances are described in this paper. (C) 2014 Published by Elsevier B.V. on behalf of China University of Mining & Technology.
