Characteristics of high level borehole deviation and its influence on extraction effect

  • In order to study the influence of high level borehole deviation on the extraction effect,borehole trajectory instrument was used to measure the borehole trajectory of high level borehole.Based on the deviation position,this paper divided the boreholes into four categories:upward deviation borehole,effective borehole,downward deviation borehole,and goaf deviation borehole.Then the extraction effect of each category was analyzed.Results show that high level boreholes have a serious deviation,the number of effective borehole is small,and goaf deviation borehole accounts for a significant proportion;fractures caused by mining activities are the main factor of borehole deviation;extraction effect drawings of these four categories boreholes have regularities and differences,which can provide the basis for optimal designs of high level borehole;gas drainage of effective boreholes is the highest and is 1.3 times higher than that of upward deviation boreholes,2.9 times higher than that of downward deviation boreholes,and 4 times higher than that of goaf deviation boreholes;the amount of gas drainage of goaf deviation boreholes is the lowest and meaningless.
