After analyzing fully-mechanized sub-level caving technology in the case of special thick and hard coal seam, it is presented that the increment of cavability of hard roof coal and available control of gas are the main difficult technology problem to be faced.

通过对特厚坚硬煤层综放开采技术的系统分析，指出提高坚硬顶煤的冒放性和瓦斯的综合治理是该条件下综放开采所面临的主要技术难题。

The application results of the N2 injection technology in Guantao reservoir of Du 84 block showed that the N2 injection technology during SAGD process was feasible and beneficial for expansion of steam chamber in sideways and increase of the horizontal sweep volume. N2 injection during SAGD process could effectively control the down flow of top water and lengthen SAGD production time by 3-4 years. Both the reservoir recovery factor and oil steam ratio could be improved.

研究结果表明，氮气辅助SAGD开采技术在杜84块馆陶油层开采中是可行的，有利于蒸汽腔的侧向扩展，增加蒸汽的横向波及体积；在SAGD过程中添加氮气能够有效控制顶水下泄，延长SAGD生产时间3～4年，提高了油藏采收率和油汽比。

This article is based on the strip mining of steeply dipping seam under villageof 230 mining area in Ge Ting coal mine of ZiBo mining group, in view of the steeply dippingseam mining under the mining geological condition of 230 mining area, we use the limittheory, the A.H.
