a core tube extending longitudinally from the proximal end to the distal end of the hose, the core tube for conveying a first fluid;
a second tube helically wound about the core tube, the second tube for conveying a second fluid;
a reinforcement layer surrounding the core tube and disposed intermediate the core tube and the second tube; and
a tubular jacket surrounding the second tube and the core tube, the tubular jacket being substantially concentric with the core tube.
2. The hose according to claim 1 , wherein the hose has a substantially cylindrical outer surface.
3. The hose according to claim 1 , wherein the second tube is at least partially embedded in the tubular jacket.
4. The hose according to claim 1 , wherein the core tube and the second tube each have an outer diameter, and the outer diameter of the core tube is at least about four times the outer diameter of the second tube.
5. The hose according to claim 1 , wherein the core tube and the second tube each have an inner diameter, and the inner diameter of the core tube is at least about four times the inner diameter of the second tube.
6. The hose according to claim 1 , wherein the second tube has a helical pitch of from about 1 to about 2 turns per 15 feet of hose.
7. The hose according to claim 1 , further comprising an additional reinforcement layer surrounding the reinforcement layer, the additional reinforcement layer being disposed intermediate the core tube and the second tube.
8. A flexible hose for separately conveying at least two fluids from a proximal end of the hose to a distal end of the hose, the hose comprising:
a core tube extending longitudinally from the proximal end of the hose to the distal end of the hose, the core tube for conveying a first fluid;
a second tube helically wound about the core tube, the second tube for conveying a second fluid; and
a tubular jacket surrounding the second tube, wherein the tubular jacket has a substantially cylindrical outer surface, and
wherein the distal end of the core tube and a distal end of the second tube terminate at a juncture where at the at least two fluids conveyed therethrough are mixed together.
9. A method of introducing different reactants into a subterraneous structure, the method comprising:
introducing a fluid handling hose to a bore hole in the subterraneous surface of an object to be mined, the fluid handling hose comprising:
a core tube extending longitudinally from a proximal end of the hose to a distal end of the hose, the core tube providing a first conduit for conveying a first reactant;
a second tube helically wound about the core tube, the second tube providing a second conduit for conveying a second reactant;
a reinforcement layer surrounding the core tube and disposed intermediate the core tube and the second tube; and
a tubular jacket surrounding the second tube and the core tube, the tubular cover being substantially concentric with the core tube;
conveying the first and second reactants to a down hole location of the bore hole; and
combining the reactants.
10. The method according to claim 9 , wherein the reactants are conveyed to the bore hole substantially simultaneously and mixing of the reactants occurs within the hole.
11. The method according to claim 9 , wherein the fluid handling hose further comprises a nozzle attached to the hose adjacent a distal end of the hose and in fluid communication with a distal end of each of the first and second conduits, and the reactants are at least partially mixed within the nozzle.
12. The method according to claim 9 , wherein the second tube is at least partially embedded in the tubular jacket and the hose has a substantially cylindrical outer surface.
13. The method according to claim 9 , wherein the core tube comprises an aperture, and a distal end of the second tube is fitted through the aperture such that at least a portion of the second tube is disposed within an interior region of the core tube.
14. The method according to claim 13 , wherein the reactants are at least partially mixed in a portion of the core tube.
15. A flexible hose for separately conveying at least two fluids from a proximal end of the hose to a distal end of the hose, the hose comprising:
a core tube extending longitudinally from the proximal end to the distal end of the hose, the core tube for conveying a first fluid;
a second tube helically wound about the core tube, the second tube for conveying a second fluid; and
a tubular jacket surrounding the second tube and the core tube, the tubular jacket being substantially concentric with the core tube,
wherein the core tube comprises a first aperture and at least a portion of a distal end of the second tube is disposed through the first aperture such that at least a portion of the second tube is located within an interior region of the core tube.
16. The hose according to claim 15 , wherein the hose has a substantially cylindrical outer surface.
17. The hose according to claim 15 , wherein the second tube is at least partially embedded in the tubular jacket.
18. The hose according to claim 15 , wherein the first aperture is located nearer to a distal end of the core tube than to a proximal end of the core tube.
19. A flexible hose for separately conveying at least two fluids from a proximal end of the hose to a distal end of the hose, the hose comprising:
a core tube extending longitudinally from the proximal end to the distal end of the hose, the core tube for conveying a first fluid;
a second tube helically wound about the core tube, the second tube for conveying a second fluid; and
an external tubular jacket surrounding the second tube and the core tube, the external tubular jacket being substantially concentric with the core tube, wherein the second tube is at least partially embedded in the external tubular jacket.
20. The hose according to claim 19 , wherein the hose has a substantially cylindrical outer surface.
