Abstract:
Aiming at the bottlenecks of lagging safety standards and the lack of quantitative performance indicators in the large-scale application of intelligent fully-mechanized excavation technology (referred to as “fully-mechanized excavation”) in coal mines, and to support the intelligent construction of coal mines and the implementation of energy security strategies, based on the development status and core intelligent requirements of intelligent fully-mechanized excavation technology, with key technical characteristics such as automatic positioning and navigation and adaptive cutting as research objects, this paper systematically compares the current situation of technical standard systems at home and abroad, and deeply analyzes the existing problems in system structure, formulation mechanism, publicity and implementation, and internationalization. Through standard gap analysis, a three-level standard framework model including “basic general, key technologies, and evaluation methods” is constructed and verified by industry. Analysis reveals that current standards safety requirements such as methane interlock shutdown, and key performance indicators including positioning accuracy of integrated navigation systems and adaptive cutting control parameters are inadequately quantified. A hierarchical standard system framework covering basic general, key technologies and evaluation methods is proposed, and the formulation and revision of a number of key standards have been completed, including MT/T 1215—2024
Tunnelling Technical Specifications for Bolter-miner System and T/CNCA 095—2024
General Safety Technical Requirements for Full-Face Tunnel Boring Machines (
TBM)
in Coal Mines. After the application of the relevant standards, the efficiency of “excavation-support-transportation” collaborative operation has been improved, the safety certification and large-scale promotion path of intelligent equipment have become clearer, and conditions have been created for mutual recognition with international standard systems. The constructed hierarchical standard framework and formulated key standards clarify the safety adaptability requirements and quantitative indicators of key performance, and enhance system synergy, equipment reliability and operation safety.
