Abstract:

In the process of coal mine production, the occurrence frequency of drilling accidents caused by the collapse of the hole, abnormal changes under the objective geological conditions or the improper technical measures under the subjective conditions are liable to cause all kinds of borehole accidents. Through the analysis of the causes of drilling collapse, the reasonable measures and methods are developed to eliminate the accident in time and to realize normal drilling.
