The panel includes a first grid disposed adjacent the first side. The panel includes a second grid disposed adjacent the second side. The first cap and the second cap and the first grid and the second grid defining a frame which envelopes and holds the core without piercing through the core. A stopping. An overcast. A method for building a wall.

1 . A panel comprising:
 a core having a top, a bottom, a first side and a second side;   a first cap disposed on the top;   a second cap disposed on the bottom;   a first grid disposed adjacent the first side; and   a second grid disposed adjacent the first side, the first cap and the second cap and the first grid and the second grid defining a frame which envelopes and holds the core without piercing through the core.   
     
     
         2 . The panel of  claim 1  wherein the first grid is attached to the first cap and the second cap. 
     
     
         3 . The panel of  claim 2  wherein the second grid is attached to the first cap and the second cap. 
     
     
         4 . The panel of  claim 3  wherein the first cap has a c shaped cross section defined by a top web and a top first flange and a top second flange, with the top web disposed on the top of the core, the top first flange disposed on the first side, and the top second flange disposed on the second side. 
     
     
         5 . The panel of  claim 4  wherein the second cap has a c shaped cross section defined by a bottom web and a bottom first flange and a bottom second flange, with the bottom web disposed on the top of the core, the bottom first flange disposed on the first side, and the bottom second flange disposed on the second side. 
     
     
         6 . The panel of  claim 5  including mortar or concrete disposed on the first grid. 
     
     
         7 . The panel of  claim 6  including a plurality of first bars disposed adjacent the first side; and a plurality of second bars disposed adjacent the second side, the first cap and the second cap and the first grid and the second grid and the first bars and the second bars defining a frame which envelopes and holds the core without piercing through the core. 
     
     
         8 . The panel of  claim 7  wherein the first bars are attached to the first cap and the second cap. 
     
     
         9 . The panel of  claim 8  wherein the second bars are attached to the first cap and the second cap. 
     
     
         10 . The panel of  claim 9  wherein each first bar is attached to the top first flange and the bottom first flange. 
     
     
         11 . The panel of  claim 10  wherein each second bar is attached to the top second flange and the bottom second flange. 
     
     
         12 . An overcast for a miner comprising:
 sidewalls;   decking disposed on the sidewalls, the decking and sidewalls formed of at least one panel comprising:   a core having a top, a bottom, a first side and a second side;   a first cap disposed on the top;   a second cap disposed on the bottom;   a first grid disposed adjacent the first side, the first cap and the second cap and the first grid and the second grid defining a frame which envelopes and holds the core without piercing through the core; and   mortar or concrete disposed on the first grid.   
     
     
         13 . A stopping for a tunnel comprising:
 a plurality of panels, at least two panels are connected together, at least one panel comprising:   a core having a top, a bottom, a first side and a second side;   a first cap disposed on the top;   a second cap disposed on the bottom;   a first grid disposed adjacent the first side, the first cap and the second cap and the first grid and the second grid defining a frame which envelopes and holds the core without piercing through the core; and   mortar or concrete disposed on the first grid.   
     
     
         14 . A method for building a wall comprising the steps of:
 placing a first panel in a desired position, the first panel comprising a core having a top, a bottom, a first side and a second side; a first cap disposed on the top; a second cap disposed on the bottom; a first grid disposed adjacent the first side; and a second grid disposed adjacent the first side, the first cap and the second cap and the first grid and the second grid defining a frame which envelopes and holds the core without piercing through the core;   placing a second panel adjacent the first panel;   connecting the first panel with the second panel; and   applying mortar or concrete to the first panel and second panel.
