深埋煤层,deep-buried coal seam
depth of coal seam煤层埋深
3)shallow thick coal seam浅埋深特厚煤层
1.Based on the high mining height of fully-mechanized top-coal caving inshallow thick coal seam and the few falling waste rock in goal, the key roof can not be supported effectively,the facture mechanical model of key roof was established.根据浅埋深特厚煤层综放开采采高大,采空区垮落矸石不充分,不能有效支撑老顶岩梁,造成老顶架后切落的特点,建立了老顶断裂力学模型,利用断裂力学理论推导了老顶的断裂步距和支架的合理工作阻力。
4)shallowly-buried and thick seam浅埋深厚煤层
5)shallow coal seam with thin bedrock浅埋深薄基岩煤层
6)deeply buried reservoir深埋储层
1.Therefore,making clear what effects the characters ofdeeply buried reservoir is important for forecasting favorable targets and gives some good advice for prospecting for oil and gas.准噶尔盆地腹部地区的储层埋深一般大于4 300 m,部分地区深度可达6 000 m左右,孔隙度和渗透率的大小变化范围也较大,弄清物性的主控因素有利于深埋储层的预测,为勘探提供依据。
