Extended bulk explosives and method of making the same

Abstract

A resulting extended bulk explosive and the process for preparing and blending oil shale particulate with bulk explosives is provided, whereby the extending bulk explosive reduces its detonation velocity. The process includes the proper preparation of oil shale granulates to gain different cost effects and performance levels with predetermined blending percentages. The oil shale granulates may be crushed, screened, dried and prepared for blending in accordance to the disclosure of the present invention.

What is claimed is: 
     
         1 . An extended bulk explosive, comprising
 a bulk explosive in the form of ANFO Prill; and   a content of oil shale granulate blended with said bulk explosive, wherein said oil shale granulate being irregularly shaped, and wherein said oil shale granulate being between 15 to 35 percent weight of the extended bulk explosive.   
     
     
         2 . The extended bulk explosive of  claim 1 , wherein the irregularly shaped oil shale granulate comprising substantially non-spherically shaped oil shale granulate. 
     
     
         3 . The extended bulk explosive of  claim 1 , wherein said oil shale granulate ranges in size of 1/32 to ½ inches. 
     
     
         4 . The extended bulk explosive of  claim 1 , wherein said oil shale granulate includes fines less than ten percent weight of the oil shale granulate. 
     
     
         5 . The extended bulk explosive of  claim 1 , wherein said oil shale granulate has a porosity of approximately 0.5. 
     
     
         6 . The extended bulk explosive of  claim 5 , wherein the ANFO Prill has a porosity of approximately 4.0. 
     
     
         7 . An extended bulk explosive, comprising
 a bulk explosive in the form of ANFO Prill; and   a content of oil shale granulate blended with said bulk explosive, wherein said oil shale granulate being irregularly shaped, and said oil shale granulate being between 15 to 35 percent weight of the extended bulk explosive, wherein said oil shale granulate ranges in size of 1/32 to ½ inches, wherein said oil shale granulate includes fines less than ten percent weight of the oil shale granulate, wherein said oil shale granulate has a porosity of approximately 0.5, wherein said ANFO Prill has a porosity of approximately 4.0.   
     
     
         8 . A method of manufacturing extended bulk explosives, comprising the steps of:
 providing bulk explosive in the form of ANFO Prill;   screening a content of oil shale for uniform size of oil shale granulate ranging in size of approximately 1/32 to ½ inches; and   blending said oil shale granulate with said bulk explosive until said oil shale granular is between 15 to 35 percent weight of the extended bulk explosive.   
     
     
         9 . The method of  claim 8 , wherein said oil shale granulate is irregularly shaped. 
     
     
         10 . The method of  claim 8 , wherein said oil shale granulate includes fines less than ten percent weight of the oil shale granulate. 
     
     
         11 . The method of  claim 8 , wherein said oil shale granulate has a porosity of approximately 0.5. 
     
     
         12 . The method of  claim 11 , wherein the ANFO Prill has a porosity of approximately 4.0.
