Underground cave local filling method

The invention relates to an underground cave local filling method. The filling method comprises the following steps: A, an upper vertical hole section communicating with a to-be-filled area of a cave is dug from the ground; B, limiting fences are installed in a guiding cave through the upper vertical hole section; and C, a filler is thrown into the space defined by the limiting fences through upper vertical holes till the filler is connected with the top wall of the cave to form the artificial surrounding rock. The underground cave local filling method is provided and used for achieving local filling of the underground cave. 本发明涉及一种地下洞穴局部填充方法，包括以下步骤：A、从地面上挖同洞穴待填充区域连通的上竖向孔段；B、经过上竖向孔段在导向洞穴内安装限位围栏；C、将填充物经上竖孔投放到限位围栏所围成的空间内至填充物同洞穴的顶壁连接在一起而形成人工围岩。本发明旨在提供一种地下洞穴局部填充方法，用于实现对地下洞穴的局部填充。
