<p>A seismic explosive charge loader and anchor is disclosed for loading and anchoring explosives in conventional containers, such as cylindrical packages and cans provided with projecting circumferential rims. The loader includes a first tubular member having an upwardly facing internal recess of sufficient diameter to loosely receive a loading pole or loading weight, and a second tubular member having a downwardly facing internal recess of sufficient diameter to fit about and receive the explosive container. A plurality of inwardly and upwardly tapered resilient gripping ribs are disposed in the internal recess and are arranged to grip smooth sides of the cylindrical explosive container and thereby securely hold it in the loader. The ribs are provided with an internal and circumferentially extending groove which receives and grips the circumferential rim or projection of the can type explosive containers. The second tubular member has an enlarged shoulder provided with an opening through it for insertion of an electric blasting cap and lead to the explosive and the central portion of the body has transversely extending appurtures therethrough through which anchor wires are disposed and which extend upwardly and outwardly for anchoring the loader in the bore hole. The loader and anchor is used with conventional wood loading poles or loading weights, wire explosion leads and the like.</p> |
