▎ 摘　　要

NOVELTY - Advanced deep hole liquid explosion fracturing structure comprises a rock tunnel hard rock section (1), where the front end of the rock tunnelhard rock section is provided with a hard rock development surface (2), the surface of the hard rock developing surface and the inner part of the stone tunnel section are provided with blast hole (3), the inside of the blast hole is filled with a coal mine liquid water gel explosive (8) through a medicine injection conduit (5), the bottom of the coal mine fluidized water-gel explosive is connected with coal mine detonating cord (4), one end of the coal mine detonating cord is set at the outer side of the blast hole the end part of the medicine injection guide pipe is provided with a medicine filling funnel. The front end of the coal mine liquid water gel explosive in the blast hole is provided with a full length bag hole sealing device. USE - The advanced deep hole liquid explosion fracturing structure is useful for downlink comprehensive digging hard rock tunnel. ADVANTAGE - The structure uses the charging method of directly injecting the coal mine liquid water gel explosive, which well overcomes the influence of the residue and local deformation in the pitching drilling hole, simplifies the charging process and reduces the deep hole loading labor intensity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for advanced deep hole liquid explosion fracturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram provides a downlink comprehensive tunnelling hard rock tunnel advanced deep hole liquid explosion fracturing structure. 1Rock tunnel hard rock section 2Hard rock development surface 3Blast hole 4Coal mine detonating cord 5Medicine injection conduit 6Charging funnel 7Frying medicine barrel 8Coal mine liquid water gel explosive 9Full length bag hole sealing machine 10Bag-bag grouting pipe 11Special blasting hole sealing grouting material
