The development of modern technologies has caused the formation of the “Industry-4.0” concept, which enables an increase in safety, reliability, energy and functional efficiency through the intellectualization of the manufacturing processes. The implementation of this concept has a special place in the coal mining industry, where one of the strategic tasks is the creation of unmanned coal mines. In this regard, the development of the existing technological structure is necessary. It requires the introduction of an improved technological structure within the framework of the “Industry-4.0” concept, which can be described as the gradual replacement of the underground personnel with appropriate sensors, detectors, and automatic control systems. In addition, the improved structures must have greater reliability and efficiency. In this article to assess the effectiveness of the coal mine working face technological structure the authors propose to use the original indicators. These indicators enable to make a comprehensive assessment of the coal mine working face technological structure “before” and “after” the implementation of the improved technological structure. The results of the analysis have made it possible to quantify the change in functional efficiency during transition to an improved technological structure.

现代科技的发展催生了“工业4.0”概念，通过制造过程的智能化，提高安全性、可靠性、能源和功能效率。这一概念的实施在煤矿行业具有特殊地位，其中一项战略任务是创建无人煤矿。在这方面，现有技术结构的发展是必要的。它需要在“工业4.0”概念的框架内引入改进的技术结构，可以说是用合适的传感器、探测器和自动控制系统逐步取代地下人员。此外，改进后的结构必须具有更高的可靠性和效率。本文作者在评价煤矿工作面工艺结构的有效性时，建议采用原始指标。这些指标能够对工艺结构改进实施“前后”的煤矿工作面工艺结构进行综合评价。分析结果使量化向改进的技术结构过渡期间功能效率的变化成为可能。
