Beschreibung
Zusammenfassung:	The invention provides a grouting method for bad drill holes. The grouting method for the bad drill hole comprises the steps that S1, relevant information is obtained; s2, according to the geological information, the mining information, the exploration information and the spatial position relation, the water inflow of the bad drill hole is calculated so as to determine the water inrush danger of the bad drill hole; s3, according to the geological information, the mining information, the deflection track of the bad drill hole and the water inflow of the bad drill hole, the bad drill hole with the water inrush risk is subjected to drilling grouting construction, so that at least part of the bad drill hole is located in the slurry diffusion radius of the drill hole drilled in the drilling grouting construction process; s4, on the basis of the lithologic parameters and/or the rock core parameters, the plugging effect of the grouting method for the poor drill holes is evaluated; wherein the inclinometry data compr
