Investigation, detection and reinforcement method for reuse of abandoned mine main roadway

Abstract

The invention belongs to the technical field of abandoned coal mine underground space utilization, and discloses an investigation, detection and reinforcement method for reuse of an abandoned mine main roadway. The general position of abandoned coal mine is determined, and after the general position is determined, the specific position of the abandoned coal mine is determined; the current situation of the roadway is explored and evaluated, the two ends of the roadway are blocked according to an evaluation result to create a closed roadway, and the roadway is remedied; after remedying is completed, the usability of the roadway is reevaluated; and after the reevaluation is qualified, the abandoned roadway is reused. The investigation, detection and reinforcement method for reuse of the abandoned mine roadway, which takes physical exploration as a main means, is used for standardizing and unifying the investigating and evaluating process before the reuse of the abandoned mine roadway, so that the construction safety in the reuse process of the mine main roadway can be better ensured, and the daily maintenance work after the construction is finished and the mine roadway is put into use is more convenient.

Description

technical field [0001] The invention belongs to the technical field of underground space utilization of abandoned coal mines, and in particular relates to a method for investigating, detecting and reinforcing the reuse of abandoned mine lanes. Background technique [0002] At present, in the past few decades, the rapid development of my country's economy must rely on the consumption of resources. Based on the basic national conditions of my country's more coal and less oil, my country's coal resources have been developed and utilized in large quantities. During this period, a large number of The mines of different sizes, these mines were closed after mining, but the main roads of these mines were permanently supported during the construction period, which means that the roads of these closed mines can still be used for a long period of time. The underground remains stable, which also offers the possibility of reusing these abandoned mine shafts. [0003] And now some special ...

Problems solved by technology

In addition, if the internal sealing conditions of the target roadway fail to meet the applicable standards, the roadway needs to be repaired, but because only the passage from the ground to the roadway with a small diameter cannot allow personnel and equipment to enter the roadway for repair work, it is necessary to use Reinforcement and repair of roadway by special means
