Caving and filling mining method
The invention relates to a caving and filling mining method which comprises the following steps: A, acquiring the position of a surface caving area and the size of a subsidence area formed after the surface caving area collapses, and calculating the volume V1 of the subsidence area; step B, preparing a filling body; and C, the filling body is piled up to the position of the surface caving area so that the subsidence area can be filled with the filling body when the surface caving area collapses to form the subsidence area, the volume of the piled filling body is V2, and the difference value between V1 and V2 is smaller than or equal to a preset value. Compared with the mode of filling after the formation of the subsidence area in the related technology, the caving and filling mining method has certain perspectiveness, filling can be carried out along with collapse, and the mining safety and the mining efficiency are improved.
本发明涉及一种崩落充填采矿方法，包括以下步骤：步骤A：获取地表崩落区的位置及所述地表崩落区塌陷后形成的塌陷区的大小，计算所述塌陷区的体积V1；步骤B：制备充填体；步骤C：将所述充填体堆存到所述地表崩落区的位置，以便所述地表崩落区塌陷形成所述塌陷区时所述充填体充填所述塌陷区，堆存的所述充填体的体积为V2，V1与V2之间的差值小于等于预设值。本发明的崩落充填采矿方法与相关技术中塌陷区形成后再进行充填的方式相比，具有一定的前瞻性，不仅可以随塌随填，提升了采矿安全性和采矿效率。
