【摘要】 针对王坪井田3号煤层底板起伏变化大,严重影响开拓及采煤巷道布置的现状,利用趋势面分析的方法,分析了井田内的构造展布规律.研究表明,井田在主向斜的基础上,存在次级背斜和NE和NW两组断裂,与本区受到多期次的构造应力场作用相吻合,得出的3号煤层底板高程二次趋势面方程,可为3号煤层开拓及采煤巷道的设计提供地质依据.更多还原

【Abstract】 The great undulating of soleplate of the third coal layer in Wangping well field badly influence exploiting disposal and excavating coal laneway.The authors analysis distributing orderliness of structure using trend surface analysis.The results indicate that the tectonic structure in the well field is dominated by broad-billed syncline overprinted by a subsidiary anticline and two groups of declinate faults respectively in NE-SW and NW-SE direction. This structural feature is coincided with tectonic stress field engendered by multi-stages tectonic movement in this area.The quadratic trend surface equation can afford geology basis for designing coal exploitin and excavating coal laneway .更多还原
