Abstract: Relevant to the present research are to improve the construction of devices for drilling wells by mechanical means and prevent the ingress of products of raise boring of wells in the disk tool and frame the space of the drilling rig. The creation of additional surface outcrop due to asymmetric speed layout of the disk tools on the expander and reducing total contact surface destructive rock elements with the face increases the efficiency of the drilling process. The aim of this work is to link the design and operating parameters of mining machines: drilling rig and scraper conveyor. The results of calculation of the amounts of coal while drilling the pilot borehole and drilling her the ex-tender reverse. Justified parameters accumulating loader, a scraper conveyor with control of incoming quanti-ties of coal from a well in a two-stage drilling and defined by its necessary length. Recommended equipment extender reverse protective devices for the unloading of bottom-hole zone of the well from the destroyed coal and eliminate a gumming of the attachment disk tools and buildings-rays of the extender. Technical solutions and test results were obtained within the base part of Ministry of Education and Science of Russia state order, project №632 “Investigation of technologies and techniques parameters for selecting and developing innovative designs to improve operating efficiency of multipurpose mining machines in Kuzbass”.
