an elongated, flexible, waterproof liner having a first, a second end, and an explosive holding portion wherein the liner is disposed on and about said tube; the first end having an aperture through which explosives can be loaded into the liner; the second end being closed and having sufficient strength to avoid rupturing when a force is exerted against the second end to dispose the liner within and along at least a portion of a borehole. ### Claim 2 A method of lining at least a portion of a borehole with an elongated, flexible, waterproof liner and filling said liner with explosives, comprising: disposing the liner an and about a tube; locating the liner at or at least partially within the entrance of the borehole, wherein the liner comprises a first end, a second end, and an explosive holding portion of the borehole; exerting force against the second end using an urging means disposed at least partly within the liner so that the liner lines at least a portion of the borehole; and ejecting explosives against said second end from said urging means whereby said liner fills with said explosives. ### Claim 3 (depends on 1) The device of claim 1 further comprising a cover disposed on and about said liner. ### Claim 4 (depends on 3) The device of claim 3 wherein said cover is not disposed on or about said first and second ends. ### Claim 5 (depends on 1) The device of claim 1 further comprising means to close said first end. ### Claim 6 (depends on 1) The device of claim 1 wherein further comprising means to close one end of said tube. ### Claim 7 (depends on 6) The device of claim 6 when the means to close is a cap. ### Claim 8 (depends on 1) The device of claim 1 wherein the liner comprises a flexible polymer. ### Claim 9 (depends on 1) The device of claim 1 wherein said second end comprises tape reinforcing. ### Claim 10 (depends on 1) The device of claim 1 wherein said second end comprises a plastic cap. ### Claim 11 A method of lining at least a portion of a borehole with an elongated, flexible, waterproof liner and filling said liner with explosives, comprising: locating the liner at or at least partially within the entrance of the borehole, wherein the liner comprises a first end, a second end, and an explosive holding portion of the borehole; exerting force against the second end using an urging means disposed at least partly within the liner so that the liner lines at least a portion of the borehole; and ejecting explosives against said second end from said urging means whereby said liner fills with said explosives. ### Claim 12 (depends on 11) The method of claim 11 wherein the urging means comprises a hose, said explosives are initially at least partially contained within said hose and said explosives are ejected from said hose by blowing air through said hose. ### Claim 13 A method of lining at least a portion of a borehole with an elongated, flexible, waterproof liner, comprising: locating a tube with a liner disposed on and about the tube at or at least partially within the entrance of the borehole, wherein the liner comprises a first end, a second end, and an explosive holding portion; exerting force against the second end of the liner so that the liner lines at least a portion of the borehole; and inserting an explosive into the liner. ### Claim 14 (depends on 13) The method of claim 13 wherein the urging means comprises a hose and force is exerted against said second end by pushing said hose against said second end. ### Claim 15 (depends on 2) The method of claim 2 wherein said urging means comprises a hose, said explosives are initially at least partially contained within said hose and said explosives are ejected from said hose by blowing air through said hose. ### Claim 16 (depends on 12, 15) The method of any one of claims 12 or 15 wherein said hose is operatively associated with an explosives feeder which feeds explosives into the hose as air is blown through the hose. ### Claim 17 (depends on 11) The method of claim 11 wherein the urging means comprises a hose, said hose also contains a detonator and a primer, and, said explosives, said detonator and said primer are ejected from said hose by blowing air through said hose. ### Claim 18 (depends on 16) The method of claim 16 wherein as said explosives are ejected from said hose, said hose moves outwardly through said first end. ### Claim 19 (depends on 17) The method of claim 17 wherein as said explosives are ejected from said hose, said hose moves outwardly from said liner through said first end. ### Claim 20 (depends on 17, 19) The method of claim 17 or 19 wherein said detonator is a non-electric detonator. ### Claim 21 (depends on 17, 19) The method of claim 17 or 19 wherein said detonator is an electric detonator and said liner is semiconductive. ### Claim 22 (depends on 12) The method of claim 12 wherein the urging means comprises a hose, said hose also contains a detonator and a primer, and, said explosives, said detonator and said primer are ejected from said hose by blowing air through said hose. ### Claim 23 (depends on 15) The method of claim 15 wherein as said explosives are ejected from said hose, said hose moves outwardly from said liner through said first end. ### Claim 24 (depends on 22) The method of claim 22 wherein as said explosives are ejected from said hose, said hose moves outwardly from said liner through said first end. ### Claim 25 (depends on 22, 24) The method of claim 22 or 24 wherein said detonator is a non-electric detonator. ### Claim 26 (depends on 22, 24) The method of claim 22 or 24 wherein said detonator is an electric detonator and said liner is semiconductive.
