摘要为了深入理解煤矿巷道储油改建工程的设计原理和关键技术，通过文献综述和具体储油工程案例归纳总结出煤矿巷道建库的关键技术及其工程应用情况：用于储油的废弃矿井选址需保证矿区地壳稳定，地质构造简单，巷道围岩岩石为坚硬岩或较坚硬岩，巷道围岩完整或较完整，围岩岩体透水性弱、有稳定地下水位；煤矿巷道围岩的渗透率离散性较大、局部或整体不满足围岩水压大于储库内油、气压之和，即Pw＞Po+ Pg时，需通过降低岩体的渗透性和流体动力遏制法进行改建，实现对储库巷道的包裹进而控制油品的泄漏；计算煤矿巷道储油能力时，需考虑巷道地质条件、水幕系统、储油库泵坑、水垫层及封堵断面等空间占用的修正系数，还应综合附近港口码头运输的油品供给量，最终确定煤矿巷道储油库的建设规模。

Abstract: In order to deeply understand the design principle and key technology of coal mine roadway oil storage and reconstruction project, the key technologies and engineering applications of coal mine roadway storage and reconstruction engineering were summarized through literature review and specific oil storage engineering cases.The site selection of the abandoned mine for oil storage should ensure that the crust of the mining area was stable, the geological structure was simple, the surrounding rock of the roadway was hard rock or relatively hard rock, the surrounding rock of the roadway was complete or relatively complete, the surrounding rock was weak in permeability and had a stable groundwater level.When the permeability of the surrounding rock of coal mine roadway was relatively discrete, and the water pressure of the surrounding rock was greater than the sum of oil and air pressure in the reservoir, it is necessary to reduce the permeability of the rock mass and carry out reconstruction by hydrodynamic containment method to realize the encapsulation of the roadway of the reservoir and control the leakage of oil products.When calculating the oil storage capacity of the coal mine roadway, it is necessary to consider the geological conditions of the roadway, the water curtain system, the corrective coefficient of the space occupied by the pump pit, the water bedding layer, and the blocking section of the oil storage reservoir, and also the oil supply volume transported from the nearby ports and wharves, so as to finalize the scale of the construction of the oil storage reservoir of coal mine roadway.

Key words: abandoned coal mine underground oil storage depot water sealing underground space utilization oil storage technology system
