<p><strong>Introduction<em>:</em></strong> Doing work on the sinking of the strong rock is always associated with huge energy consumption. In particular due to the fact that in most modern roadheader destruction produced by cutting. A cutting rocks process is very energy-intensive and demanding to the quality of the cutting tool. Due to the nature of this method combines must have a very large mass and dimensions. These shortcomings are not critical during the passage of the long straight tunnel. But for sinking short process areas required technological machine considerably smaller dimensions. Such an instrument can be a roadheader with planetary shock the shearing executive body.</p>
<p><strong>Objective<em>:</em></strong> Development of miner combine the concept of planetary shock the shearing executive body.</p>
<p><strong>Method<em>:</em></strong> In order to achieve this goal have been used such scientific methods as analysis and synthesis, generalization, analogy, comparison, system approach. The analytical part of the work was carried out by examining the kinematics of the executive bodies for further optimization of their trajectories by SQP method.</p>
<p><strong>Results<em>:</em></strong></p>
<ol>
<li>Describe the basic structure of the planetary shock-shear body heading machine;</li>
<li>a study of the kinematics of the executive bodies;</li>
<li>The obtained optimal values of some parameters of planetary impact-shear body.</li>
</ol>
<p><strong>Conclusion<em>:</em></strong></p>
<p>As a result of the research has been the necessity to develop compact tunneling machines, based on the destruction of rock shock-mechanical process that allows point-and, at the same time, uniformly release the impact energy across the bottom surface. For uniform load distribution on the surface to be treated the optimum rotational speed of the executive bodies of the combine were calculated (SQP method). Presented article is a starting point for further development of the tunneling machines with planetary shock the shearing executive body.</p>trajectory of movementroadheaderactuatorspeed bumpsplanetary executive bodyspeedoptimization criterionoptimization techniquesтраектория движенияпроходческий комбайнрабочий органчастота ударовпланетарный исполнительный органскорость движениякритерий оптимизацииметоды оптимизации[Biggs M.
