【摘要】 在分析大量调研资料和实地观测数据的基础上,应用地表移动预计系统对山区采煤地裂缝的成因从实例和预计进行对比分析,探讨了采动裂缝与地表移动变形的关系,并对工作面进行裂缝预测。结果表明:在充分采动区,预计与实测吻合度较高,在非充分采动区,预计与实测差异较大。并对未采工作面进行预测,从而为矿区采取有效的防灾减灾措施以及为地质灾害的评价提供一定的依据。更多还原

【Abstract】 Based on analyzing a great deal of investigation datum and practical observation,crack genetic analysis and predictability in mountainous excavate coal areas were contrasted with an example by anticipate surface movement system,the relations between mining cracks and surface movement deformation was discussed,and the surface cracks for the concrete working face were also forecast.The results indicate that: in the full subsidence area,the forecasting fits well with practical observation,and in the other areas,there is a distinct discrepancy.The non-mining working face was also forecasted,so that some basis was provided for mining area to adopt effective measures,evaluate and prevent(or decrease) the geology disaster,to keep the mining area’s continuous development.更多还原
