The upward horizontal layered filling mining method is a mining method that divides the ore block into ore rooms and pillars, and mines them layer by layer from bottom to top. After mining one or several layers, timely filling is carried out to maintain the surrounding rock. The following is a detailed introduction to this mining method:

Mining steps:

Firstly, divide the ore block into two parts: the ore room and the ore pillar.

The first step is to extract the mining room in layers from bottom to top. As the work progresses upwards, fill the goaf layer by layer and leave space for further mining.
The filling body not only maintains the two surrounding rocks, but also serves as a working platform for mining. The collapsed ore falls onto the surface of the filling material and is then transported mechanically to the ore chute.
When the mining room reaches the top layer, top filling is carried out.
The second step is to recover the mining pillars, usually after the mining is completed. The recovery method can be the filling method or other suitable methods.
Filling method:

There are various filling methods for mining rooms, including dry filling, hydraulic filling, and cemented filling.
The function of the filling body is to support the two sides of rocks in the goaf, creating a foundation for the continued layered mining on top.
Applicable conditions:

The upward horizontal layered filling mining method is suitable for inclined and steeply inclined ore bodies where the ore is stable but the surrounding rock is unstable.
It can also adapt to ore bodies with irregular shapes and large branching and composite changes.
In addition, this method is also applicable to the mining of precious and rare metals with low ore loss, low impoverishment, high ore grade, and high value, as well as steeply inclined medium thick to extremely thick and multi-layered ore bodies with slightly poor stability or moderate stability in the rocks of the upper and lower walls of the ore body.
Features and advantages:

This mining method effectively maintains the stability of the surrounding rock and reduces the loss and impoverishment of the ore body by timely filling the goaf.
It provides a safe and efficient method for mining high-grade and high-value ores.
At the same time, this method also has strong adaptability and can handle ore bodies with complex shapes and large changes.
In summary, the upward horizontal layered filling mining method is an efficient and safe mining method suitable for specific conditions.
