Abstract：In order to guide the mine rescue, the parameters to determine the rescue drilling positioning accuracy are discussed, the factors affecting the rescue drilling accuracy are analyzed with error theory, the reasonable value of the rescue drilling construction error are studied, and the determination methcd for traditional drilling construction error are improved and optimized. Lastly, its application is illustrated by examples. The study has shown that the drilling construction error must be controlled within a reasonable limit as long as the staff position and drilling setting-out accuracy are certain.
