Production and application of fire resistant erosion control mat

Abstract

A fire resistant ground erosion control mat assembly. The mat assembly includes an inner layer of fire resistant milled stone mineral wool material with an upper and a lower layer of supportive nets. Each of the upper and lower nets consist of fire resistant milled mineral foraminous nettings to enable passage of light and water therethrough as a ground positioned emplacement of the inner layer.

1 . An elongated, fire resistant light-transmissive ground erosion control mat assembly comprised of:
 an elongated, fire resistant, light-transmissive lower, foraminous, supportive net;   an elongated, fire resistant, light-transmissive upper, foraminous supportive net;   an elongated, fire resistant, light-transmissive innermost layer sandwiched between the light-transmissive lower foraminous support net and the light-transmissive upper support net, and wherein the innermost layer is comprised of a rock wall vegetation supportive matrix, and wherein the light transmissive lower foraminous supportive net end of the light-transmissive foraminous upper supportive nets are each environmentally degradable.   
     
     
         2 . The elongated, fire resistant light-transmissive ground erosion control mat assembly as recited in  claim 1 , wherein the elongated fire resistant light-transmissive lower foraminous supportive net is formed from an elongated single source fiber creating an elongated continuous three-dimensional matrix. 
     
     
         3 . The elongated, fire resistant light-transmissive ground erosion control mat assembly as recited in  claim 1 , wherein the elongated fire resistant light-transmissive upper foraminous support net is formed from an elongated single source fiber creating an elongated continuous three-dimensional matrix. 
     
     
         4 . The elongated, fire resistant light-transmissive ground erosion control mat assembly as recited in  claim 1 , wherein the elongated fire resistant light-transmissive upper foraminous support net and the elongated fire resistant light-transmissive lower foraminous support net are tack welded together at disparate locations thereon. 
     
     
         5 . The elongated, fire resistant light-transmissive ground erosion control mat assembly as recited in  claim 1 , wherein the mat assembly is between about 0.1 to about 2.0 inches thick. 
     
     
         6 . The elongated, fire resistant light-transmissive ground erosion control mat assembly as recited in  claim 1 , having a light-transmissivity thereacross of between about 30 to about 80%. 
     
     
         7 . The elongated, fire resistant light-transmissive ground erosion control mat assembly as recited in  claim 1 , wherein the innermost layer of rock wool is comprised of a fiberized Basalt. 
     
     
         8 . The elongated, fire resistant light-transmissive ground erosion control mat assembly as recited in  claim 1 , wherein the elongated fire resistant light-transmissive lower foraminous supportive net is comprised of an air and light-transmissive layer of metal selected from the group consisting of stainless steel, galvanized steel, aluminum and tin. 
     
     
         9 . The elongated, fire resistant light-transmissive ground erosion control mat assembly as recited in  claim 1 , wherein the elongated fire resistant transmissive lower foraminous supportive net is comprised of an air and light-transmissive layer of fire resistant material selected from the group consisting of plastic or polyvinyl chloride. 
     
     
         10 . The elongated, fire resistant light-transmissive ground erosion control mat assembly as recited in  claim 8 , wherein the elongated fire resistant light-transmissive lower foraminous supportive net is comprised of a chain link arrangement having openings therethrough of a range of from about one quarter of an inch to 1 inch there cross. 
     
     
         11 . The elongated, fire resistant light-transmissive ground erosion control mat assembly as recited in  claim 7 , wherein the fiberized Basalt is processed into a longer fiber by a melting of a slag of the Basalt through a treatment chamber. 
     
     
         12 . The elongated, fire resistant light-transmissive ground erosion control mat assembly as recited in  claim 11 , wherein the longer fiber of the fiberized Basalt has a thickness of between about 0.01 inches to about 0.1 inches thick, and has a length of from about 0.25 inches to about 12 inches.
