薄煤层综采工作面高效开采装备适应性分析与改进

Adaptability Analysis and Improvement of High Efficiency Mining Equipment for Thin Coal Seam Comprehensive Mining Face

摘要

薄煤层占我国煤炭可采储量的20%，是我国能源安全的重要战略资源，高效开采薄煤层有利于提高资源采出率，促进煤炭行业绿色转型。由于受采掘空间狭小、地质情况复杂等种种原因，造成“采厚弃薄”的现象严重，开采效率低、智能化水平低。综采装备是薄煤层高效开采的关键支撑，它的好坏直接影响到开采的安全性和经济效益。本文根据薄煤层地质特点和开采要求，分析采煤机、液压支架、刮板输送机的适应性不足之处，剖析短板原因，提出改进措施和创新方向，结合工程实践检验效果，为装备更新升级和规模化开采提供理论和工程上的参考。

Abstract

Thin coal seams constitute 20% of China’s recoverable coal reserves, representing a vital strategic resource for national energy security. Efficient mining of these seams enhances resource recovery rates and facilitates the green transition of the coal industry. However, constrained by limited mining space and complex geological conditions, the “thick seam mining and thin seam abandonment” phenomenon persists, resulting in low extraction efficiency and underdeveloped intelligent systems. As the cornerstone of efficient thin coal seam mining, fully mechanized mining equipment directly impacts both operational safety and economic viability. This study examines the inadequacies of coal cutters, hydraulic supports, and scraper conveyors in thin coal seam mining, identifies root causes of these limitations, and proposes targeted improvement measures and innovative solutions. Through practical engineering validation, the research provides theoretical and operational references for equipment modernization and large-scale mining operations.
