Abstract:In order to ensure the mining safety of the mining face in the coal mine production process,before the mining operation of the coal face,it is usually necessary to carry out geophysical exploration on the water-rich condition and structural occurrence of the coal seam roof,and make drilling design for drilling verification according to the geophysical exploration results and the hydrogeological conditions of the coal mine,that is,water exploration and release operation.Zhaojin Coal Industry Co.,Ltd.encountered construction difficulties such as hole collapse and hole collapse due to the use of water supply cooling and slag discharge in the past drilling operation.Combined with the formation analysis in the region,it is found that the top of the coal seam of Fuxian Formation of the mine has the characteristics of easy expansion and collapse in contact with water,which is easy to cause the accident of hole collapse and hole collapse in the construction of water exploration and water release drilling.According to the characteristics of mudstone in coal seam roof,the construction technology has been changed through the water exploration and release construction of 301 working face,which provides a feasible basis for the water exploration and release construction of this mining area in the future.
