巨厚表土层条件下综合机械化放顶煤开采地表沉陷规律研究

摘要

This paper research and analyzed surface subsidence law of comprehensive mechanized caving mining under thick alluvium in new Julong company ,and obtained the general rules and characteristics of ground surface movement and the various parameters of the geological conditions, and provided reliable technical data for safe production of the mine in similar mining area"three under"mining work.%该文通过新巨龙公司巨厚表土层条件下综合放顶煤开采地表变形观测资料的分析研究得出了该地质条件下地表移动的一般规律和特点，求得该条件下的各类参数，为矿井安全生产和类似矿区的“三下”采煤等工作提供了可靠的技术数据。
