摘　　要：油页岩技术可采系数是将油页岩资源转化为油页岩技术可采资源的关键参数。由于我国油页岩井下开采少，且规模小，无经验借鉴。油页岩开采技术与煤炭开采技术相类似，通过分析油页岩技术可采系数的影响因素，参照煤炭规范中所规定的煤炭地下及露天开采回采率标准，建立了不同条件（开采方式、厚度、倾角和地质类型）、不同资源类型的油页岩技术可采系数的取值标准。油页岩技术可采系数彰响因素确定为开采方式（露天开采和地下开采）、厚度（薄层、中厚层和厚层）、倾角（缓倾斜、倾斜和急倾斜）和地质类型（简单、中等和复杂）；不同资源类型（13种）确定技术可采系数时，选取了不同的可信度系数（1．0～0．5）。油页岩露天开采技术可采系数确定为95．0％～42．5％，地下开采油页岩技术可采系数确定为75％～22．5％。并以吉林省汪清罗子沟盆地油页岩资源评价为例进行了具体应用。The oil shale technology mining coefficient is the pivotal parameter when the oil shale resources are converted into the oil shale technique mining resources. Because the underground oil shale mining in our country is limited either in mining number or at mining scale, there is no experience as reference, The oil shale mining techniques are similar to the coal mining techniques. By analyzing the influence factors of the oil shale technique mining coefficient and referring to the recovery criterion of underground and surface coal mining which is regulated in the coal mining criterion, the choose value criterion of the oil shale technique mining coefficient was established under different conditions （the mining manner, thickness of oil shale layer, obliquity and geologic types） and different resource types. The influence factors of oil shale technology mining coefficient consist of mining manners （surface or underground min- ing）, thickness （folium, middle-thick layer or thick layer）, obliquity （slow slope, slope or urgent slope） and geologic types （simpleness, middling or complexity）. Different reliability coefficients （1.0- 0.5） were specified when the oil shale technology mining coefficient was ascertained for different resource types （13 kinds）. The technology mining coefficients of oil shale at surface and underground are ascertained between 95.0% and 42.5% and between 75% and 22. 5%,respectively. Finally, this re- source evaluation process was applied in Luozigou Basin in Wangqing, Jilin Province as an examnle.
