摘　　要：在分析煤矿安全科技工作现状和趋势基础上 ,介绍了近年来我国瓦斯灾害防治技术研究取得的进展和新成果。通过“十五”科技攻关项目的研究 ,提出了瓦斯煤尘爆炸危险性评价方法 ,研究出了基于瓦斯地质、地质动力区划、电磁波探测方法的煤与瓦斯突出区域预测技术和基于AE声发射、电磁辐射和瓦斯涌出等原理的煤与瓦斯突出非接触连续预测技术 ,实验成功了高瓦斯煤层群开采保护层瓦斯灾害综合防治及顺煤层强化抽放等技术 ,开发了矿井通风系统监测、可靠性评价分析及决策控制技术。另外还分析了我国煤矿安全所面临的挑战和急需开展的科技研究工作。Based on analysis on the current situation and developing tendency of work safety in coal mines, developments and new achievements in the aspect of researches on gas control technology in recent years in China were introduced. When tackling the brainstorm state projects of the 'Tenth Five-year Plan' , findings have been worked out such as the method to evaluate hazards of gas and coal dust explosion, regional predicting technology of coal-burst and gas-burst based on detecting methods of gas geology, geo-dynamics division and detection with electromagnetic wave and coal-burst and gas-burst non-contact continuous predicting technology based on principles of AE acoustic emission, electromagnetic radiation and gas inrush. Technologies of comprehensive gas disaster prevention and control when mining in protection layers among seam groups with high gas concentration as well as strengthening gas extraction along coal seams have been proven successfully. Monitoring on mine ventilation system, evaluation and analysis on reliability and decision-making control technology have also been developed. In addition, analysis on challenges of work safety in China's coal mines as well as scientific research work in urgent need of development has been made.
