Abstract: 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 mining), 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 resource evaluation process was applied in Luozigou Basin in Wangqing, Jilin Province as an example.

Key words: oil shale, mining resources, technology mining coefficient
