| 1 | Preparation and coking properties of coal maceral concentrates显示文摘The concentrates with different maceral contents were obtained from Kailuan coking coals with different coal ranks(Ro;ranvarying from 0.88%to 1.73%)by float–sink separation in lab.Then these concentrates were characterized by proximate analysis,ultimate analysis,petrography analysis and coking index determination.The results show that the vitrinite is characterized as nature of lower carbon content,higher hydrogen content,higher volatile matter and stronger caking property compared to inertinite.The relationships between variation rate of volatile matter and maximum volatile matter and coal ranks are identified,and a linear model is developed for fast determination of the maceral contents.Compared to inertinite-rich concentrate,the blending ratio of vitrinite-rich concentrate is increased by 13%,which is considered to be a potential technique based on maceral separation for expanding the coking coal resources. | Zhang Lei Liu Wenli Men Dongpo | 2014 | International Journal of Mining Science and Technology2014，24，1： | 12 |

| 3 | 中国煤炭工业高质量发展测度及耦合协调分析——基于2000-2019年数据的实证研究显示文摘本文从经济效益、创新发展、集约发展、安全发展、绿色发展和高效发展6个维度构建了煤炭工业高质量发展评价指标体系,通过熵权法、理想点法(TOPSIS)和耦合协调度模型测度并深入分析了我国煤炭工业2000—2019年的高质量发展状况。结果表明:煤炭工业高质量发展成效显著,但产业规模与高质量发展水平呈现明显的不同步现象;在不同的发展阶段,煤炭工业高质量发展的主动力和“短板”有所不同;煤炭工业高质量发展的6个维度在研究期内均有不同程度上的提升,但绿色发展和高效发展的提升速度相对较慢;煤炭工业6维度发展耦合协调度稳定上升,但尚未进入“优质协调发展”阶段,协调发展水平有待提升。 | 杨跃翔 王锟桠 任蕾 | 2021 | 矿业科学学报2021，6，6： | 9 |

| 6 | 紫外-微波复合诱变选育溶煤菌株及其溶煤产物分析显示文摘生物转化是煤炭清洁温和利用的有效途径之一.为提高神府煤的生物溶解率及产物定向转化的选择性,分别用沙门氏菌、黄杆菌、大肠杆菌、枯草杆菌、金黄色葡萄球菌、黑曲霉菌及云芝菌对神府煤进行溶解.以最佳溶煤菌为出发菌株,利用紫外-微波复合诱变,选育更高效的溶煤菌株进行煤的生物转化,用FTIR和GC/MS对溶煤产物进行了分析.结果表明,紫外-微波复合诱变对云芝菌具有明显的诱变效应,复合诱变后的云芝菌对神府煤具有最好的溶解效果,其溶煤率从原来的41.3%提高到54.2%.FTIR和GC/MS分析表明,神府煤经生物转化,产物的芳香类物质相对含量降低,而烷烃、酰胺、烯烃、醇及醚类物质含量增多. | 赵玮钦 马骁 侯彬彬 岳子林 周安宁 | 2018 | 湖南科技大学学报(自然科学版)2018，33，1： | 2 |
| 7 | CO emission in the air return corner of the working face in shallow burial mining areas显示文摘In shallow burial mining areas, abnormal CO emission and the spontaneous combustion of coal are great threats to safety production at a fully-mechanised working face. In order to prevent the CO concentration in the air return corner from exceeding the critical limit, the paper studied the CO emission regularity and characteristics through theoretical analysis, experimental research and field observation. The results show that the main sources of CO emission were the spontaneous combustion of coal in the goaf and the exhaust emissions coming from underground motorised vehicles. The effect factors of CO emission were also investigated, such as seasonal climate changes, the advancing distance and advancing speed of the working face, the number of underground motorised vehicles and some other factors. In addition to these basic analyses, the influence mechanism of each influence factor was also summarised theoretically. Finally, this study researched the distribution and change law of CO concentration in the fully-mechanised working face in two aspects: controlling the change of monitoring points and time respectively. The research results provide a theoretical basis for preventing the CO concentration from exceeding the critical limit in the air return corner and reducing the possibility of spontaneous combustion of coal. Additionally, the results also provide important theoretical and practical guidelines for protecting miners' health in modern mines featuring high production and high efficiency all over the world. | Botao Qin Yi Lu Yuwei Jia | 2014 | International Journal of Mining Science and Technology2014，24，5： | 1 |
