Irregular goaf cave probing method

The invention relates to the technical field of detection, and specifically relates to an irregular goaf cave probing method. The technical scheme employed by the invention comprises the following concrete steps: a, a drilling grouting probing method involves performing drilling probing on an area surface possibly with caves existing thereon and then carrying out aperture enclosing probing grouting through employing grouting pressure of 0.5 to 1.0 MPa on boreholes so as to probe the caves possibly existing in the scope within a radius of 2.0m around each borehole, wherein obvious positions with extremely large grouting absorption, abnormal grounding amounts and collapse conditions can be determined as suspected cavities and caves; and b, by taking the boreholes of the suspected cavities and the caves as centers, holes are arranged around according to a cross form, and hole arrangement is intensified according to such a method that hole intervals are gradually decreased towards the direction of the suspected c
