The paper deals with the application of air and hydraulic hammer tools for the destruction of hard rock in the mode of continuous operation. The regularities of the effectiveness of demolition of rock, depending on the shape and angle of the executive body to the surface are deter-mined. There are recommendations for use the executive bodies of shock mining machines in the article.
The article studies the influence of the mineral body offsetting on the schedule of current volumes of overburden stripping. This issue has not been specially studied in previous publications by various authors. The issue of replacing areas by linear sections making up the pit walls has been justified in calculation of the current overburden volumes in cross-sectional plan. A corresponding dependence has been received in order to create a schedule for minimal current overburden volumes and a schedule for changes in current volumes depending on the rising depth. The proposed approach helps to establish general regularities which can be used in selecting parameters and directions of mining operations.
Problems of branch are formulated, decisions of the cores from them are offered. Ecologically pure technology of development of rocky rocks allowing considerably is presented to lower a level of losses and contaminations at extraction of minerals. The brief review of practice of application of the presented technology abroad is given. The technique of a choice of the process equipment is offered. Advantages of the offered technology are noted.
