The article discusses feasibility of smart and efficient resource use in the machine works–mine cluster based on the concept of lean and low-waste manufacture. Products of the machine works (pumps, coal pumps, fans, winch arrangements, buckets, conveyors, rock-breaking tools etc.) for the mining industry feature a high resource consumption and a rather short life. The latter is governed by a set of specific factors, namely: rock pressure, rock bursts and gas outbursts, high gas and dust content of air, higher moistness of underground openings and rock mass, high abrasivity of water, air, rocks etc. As a consequence, machines, mechanisms and tools go unserviceable very fast and pass into waste. At the same time, if treated sparingly and economically, many types of production waste have a high chance of recovery up to the level of good condition and return to a production cycle, while some waste items can be brought to even a better condition with new properties. To this effect, cyclic technologies of higher resource-saving level are required. The feasibility of waste recycling and resource efficiency enhancement in the machine works–mine system is discussed as a case-study of a rock-breaking tool. The proposed structural properties and technological capabilities form a three-level waste recycling system for shearer picks, which provides conditions for prudent handling of metals involved in the process of rock fracture—steel and hard alloy. A long-term life cycle of the metals in the mining industry is ensured, at the decreased metal losses, increased level of non-waste operation of coal mines, and at the better performance of the picks. Development of new designs and technologies by mechanical engineers in cooperation with mining engineers makes the low-waste mining industry in Kuzbass realistic.
