Construction method of consolidating horizontal directional drilling hole by grouting coal seam baseboard

ActiveCN102134967AAchieve consolidationAdjustable drilling directionSurveyDirectional drillingGeomorphologyBaseboard
The invention relates to a construction method of consolidating horizontal directional drilling holes by grouting a coal seam baseboard. Along with the continuous extension of coal mining depth and the continuous enlargement of the mining range, crustal stress is enlarged, and the number of abnormal geologic bodies is gradually increased, water pressure is gradually enhanced, hydrogeologic conditions become more and more complex, and water-inrush threat becomes more and more serious. The construction method provided by the invention comprises the following steps of: drilling holes in a coal seam by developing a drill field in a coal heading of a working surface, wherein the drilling direction points to a water resisting layer and a water bearing layer of the coal seam baseboard; rotatably drilling the coal seam baseboard for a certain depth to carry out hoist drilling and broaching, installing a primary hole sealing sleeve to seal the hole by grouting, cleaning the bottom of the hole after the grout is solidified; and then consolidating the hole by a primary sleeve, consolidating the hole by a secondary sleeve, and carrying out directional drilling to make the drilling hole extend along a preset consolidating layer according to the designed track to finally form the drilling hole. In the invention, the entire consolidation of the coal seam baseboard of the regional working surface is realized through designing the drilling hole track, determining the drilling hole consolidating radius and reasonably arranging the directional drilling according to the analysis to the water resisting layer and the water bearing layer.
