He has made significant contributions to the field of underground rock blasting, holding 2 patents that showcase his innovative methods. His work is particularly relevant to industries that require efficient and safe blasting techniques.
Latest Patents
Freeman's latest patents focus on a method of underground rock blasting. This method involves drilling boreholes in a rock mass from a drive defining face. Each borehole is loaded with at least one charge of explosive material, and at least one detonator is placed in operative association with each charge. A sequence of at least two initiation events is conducted to blast the rock mass, where only some of the charges are initiated during each event. This allows for a controlled and discrete user-controlled initiation process. Notably, in one of the initiation events, a stranded portion of the rock mass, such as a pillar, is created. This portion can be blasted in subsequent initiation events without personnel needing to access it, enhancing safety. The detonators used in this method may also be wireless, further improving operational efficiency.
