Abstract: A method for mining a mineral deposit underground in a vein having an underburden and an overburden which comprises boring a pilot hole into the vein between the underburden and the overburden. The thickness of the material is then measured at predetermined distances along the pilot hole, between the pilot hole and the overburden, and between the pilot hole and the underburden. The information measured is stored in a storage mechanism which relates the measurements to the distance in the borehole. A mining machine is then controlled in accordance with the distance between the borehole and the overburden, and the borehole and the underburden. The invention further contemplates a method of mining where the tunnel being mined is sealed off and filled with an inert atmosphere. This method will provide an explosion-free environment during the mining operation.
Abstract translation: 一种用于在具有下覆层和上覆岩层的静脉中地下开采矿床的方法，其包括将引导孔钻入下伏岩层和上覆岩层之间的静脉中。 然后沿着导向孔，导向孔和覆盖层之间以及导向孔和下伏之间的预定距离测量材料的厚度。 测量的信息被存储在将测量值与井眼中的距离相关联的存储机构中。 然后根据钻孔和覆盖层之间的距离以及钻孔和下埋层来控制采矿机。
