Embodiment Construction
[0033] See attached figure 1 , which describes a preferred embodiment of the method for preventing roadway lag water inrush by optimizing support parameters in deep mining according to the present invention. The method includes five steps, namely:
[0034] (1) Determine the preliminary support plan;
[0035] (2) Optimization of bolt support parameters;
[0036] (3) Determination of support scheme and support parameters;
[0037] (4) Aquifer detection and grouting reinforcement in fault fracture zones;
[0038] (5) Gangue filling in roadway.
[0039] Each step is further described in detail below.
[0040] The steps of determining the preliminary support scheme include the following process contents:
[0041] ①Preliminary support of roadway under special geological conditions
[0042] During the excavation process, use underground seismic detection, Rayleigh wave detection or transient electromagnetic detection methods to detect geological anomalies in fault lithology ch...
