Downward fully-mechanized excavation hard rock roadway advance deep hole liquid explosion fracturing structure and method thereof
The invention provides a descending fully-mechanized excavation hard rock roadway advanced deep hole liquid explosion fracturing structure, and belongs to the technical field of rock roadway deep hole explosion. Comprising a rock roadway hard rock section, a hard rock tunneling face is arranged at the front end of the rock roadway hard rock section, blast holes are formed in the surface of the hard rock tunneling face and the interior of the rock roadway hard rock section, the interiors of the blast holes are filled with coal mine liquid water-gel explosives through explosive injection guide pipes, and the bottoms of the coal mine liquid water-gel explosives are connected with coal mine detonating cords. One end of the coal mine detonating cord is arranged on the outer side of the blast hole, the end of the explosive injection guide pipe is communicated with an explosive loading hopper, and an explosive barrel is arranged above the explosive loading hopper. The invention further provides an advanced deep hole liquid explosion fracturing method for the descending fully-mechanized excavation hard rock roadway. According to the method, by adopting the charging mode that the coal mine liquid water-gel explosive is directly poured, the influence of residues and local deformation in the downward drilling hole is well overcome, the charging procedure is simplified, and the labor intensity of deep hole charging is reduced.
本发明提供了下行综掘硬岩巷道超前深孔液爆压裂结构,属于岩巷深孔爆破技术领域。包括岩巷硬岩段,所述岩巷硬岩段的前端设置有硬岩掘进面,所述硬岩掘进面的表面和所述岩巷硬岩段的内部开设有炮孔,所述炮孔的内部通过注药导管填充设置有煤矿液体水胶炸药,所述煤矿液体水胶炸药的底部连接有煤矿导爆索,所述煤矿导爆索的一端设置在所述炮孔的外侧,所述注药导管的端部连通设置有装药漏斗,所述装药漏斗的上方设置有炸药桶。本发明还提供了下行综掘硬岩巷道超前深孔液爆压裂方法。本发明通过采用煤矿液体水胶炸药进行直接灌注的装药方式,较好地克服了俯向钻孔内残渣及局部变形影响,简化了装药工序,降低了深孔装药劳动强度。
