Construction method for backfilling of mine tunnel by means of foam concrete

The invention discloses a construction method for backfilling of a mine tunnel by means of foam concrete. The construction method comprises the following steps of construction of a blockage wall of alower fracture surface, backfilling of foam concrete of the lower fracture surface, removal of a temporary support, construction of a blockage wall of an upper fracture surface, and backfilling of foam concrete of the upper fracture surface. The construction method for backfilling of the mine tunnel by means of foam concrete has the advantages that operation is easy, and the construction cost is low. 本发明公开了一种采用泡沫混凝土回填矿山法隧道的施工方法，包括以下步骤：下断面封堵墙砌筑，下断面回填泡沫混凝土，拆除临时支护，上断面封堵墙砌筑，上断面回填泡沫混凝土，本发明具有操作简单，施工成本低的优点。
