| 摘要: |
| 在对国内外突出危险性区域预测理论和预测技术进行系统研究的基础上，基于白山坪矿井延深水平（-400～-600 m）的煤层赋存、顶底板条件、地质构造条件等情况，以延深水平开拓前与开拓后为时间区段，分别应用多种现有区域预测技术与方法进行水平、新采区和工作面的突出危险性区域预测，以提供科学、准确的预测结果，为科学合理采用防突技术提供关键依据.在对矿井延深水平3162工作面煤巷掘进的效果考察中发现，在采用区域综合预测结果分析后，仅对预测有突出危险性区域进行局部防突卸压后，经钻屑指标法对全工作面进行效果检验，其钻屑瓦斯解吸指标△h2和每个钻孔的最大钻屑量Smax均小于《防突规定》中的参考临界值，取得理想卸压效果. |

| Abstract: |
| On regional prediction of outburst danger at home and abroad on the basis of studying the theory and technology of the forecasting system, based on the Bai Shan ping mine deep level (400 ~ 600 m), roof and floor of coal seam occurrence condition, geological structure, etc., to the deep level development before and after the development for the time segment, a variety of existing regional prediction technology and method were applied, to decide the new mining area and forecasting outburst danger area of working face, to provide scientific and accurate prediction result, to provide the key basis for the scientific and reasonable using outburst prevention technology. On the level of extending the deep in the mine 3162 working face in the investigation of effects of excavating in coal roadway, it found that after the regional comprehensive prediction analysis, only to predict outburst danger area of local outburst prevention after unloading, the drilling cuttings index method is carried out on the whole face effect test, the drilling cuttings gas desorption index Δ h2 and the maximum drilling cuttings Smax of every hole is smaller than the reference in the outburst prevention provisions on the critical value, ideal pressure relief effect is obtained. |
