Abstract
A mat assembly including a planar mat body formed to cover a preselected area of a surface region. The preselected area partially defines a volume of ground to be broken by explosion therein. The mat body includes one or more layer elements. The mat body has an engagement surface for engagement with the preselected area. The mat assembly includes a skirt element connected with the mat body having an external portion extending from the mat body, for at least partially restraining matter ejected from the volume of ground upon initiation of the explosion.
Claims15
A mat body to be positioned on a surface region, the mat body comprising at least one layer element comprising at least one abrasion-resistant surface, wherein the mat body has an area density up to 2.2 pounds per square foot.
A mat assembly formed to be positioned relative to a preselected area of a surface region, the preselected area partially defining a volume of ground to be broken by explosion therein, the mat assembly comprising:
- a planar mat body formed to cover the preselected area, the mat body comprising at least one layer element defining an engagement surface for engagement with the preselected area;
- and
- a skirt element connected with the mat body, the skirt element comprising an external portion extending from the mat body for at least partially restraining matter ejected from the volume of ground, upon initiation of the explosion.
A mat assembly formed to be positioned relative to a preselected area of a surface region, the preselected area partially defining a volume of ground to be broken by explosion therein, the mat assembly comprising:
- a planar mat body formed to cover the preselected area, the mat body comprising at least one layer element;
- a skirt element connected with the mat body, the skirt element comprising an external portion extending from the mat body;
- and
- at least one anchor element, for securing the mat body to a preselected location on the surface region relative to the preselected area,
- wherein the mat body and the external portion are configured to at least partially restrain matter that is ejected from the volume of ground, upon initiation of the explosion.
A mat assembly formed to be positioned relative to a preselected area of a surface region, the preselected area partially defining a volume of ground to be broken by explosion therein, the mat assembly comprising:
- a planar mat body formed to cover the preselected area, the mat body comprising at least one layer element;
- a skirt element connected with the mat body, the skirt element comprising an external portion extending from the mat body and located at least partially transverse to said at least one layer element;
- and
- at least one anchor device, for engaging a predetermined part of the external portion at a preselected location on the surface region relative to the preselected area,
- wherein the mat body and the external portion are configured to at least partially restrain matter that is ejected from the volume of ground, upon initiation of the explosion.
