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.
