Problems solved by technology

[0002] When mining extremely unstable, thick, large and low-grade ore bodies, the caving method is generally used for mining. However, caving mining will cause surface subsidence and affect sustainable development. Especially when mining under farmland, the surface subsidence is not allowed, so filling mining is required mining method, filling mining method has high cost and low production efficiency

Embodiment Construction

[0019] Take the mining method of the Dazhuohe Iron Mine Area of ​​Shandong Shengda Mining Co., Ltd. as an example to specifically illustrate the ore pillar pre-isolation segmentation block filling mining method of the present invention:

[0020] The Dazhuohe Iron Mine Area of ​​Shandong Shengda Mining Co., Ltd. is located about 1km west of Dazhuohe Village, Tushan Town, Laizhou City, at the junction of Yantai City and Qingdao City. The strike length of the ore body is 2100m, the inclination angle is 0°~20°, and the thickness varies greatly. The maximum thickness is 77.74m, the minimum thickness is 2.98m, and the general thickness is 10~30m. Dazhuohe Iron Mine has 44.939 million tons of iron ore resource reserves, with an average grade of TFe28.97%. It is mined by pillar pre-isolation, segmented and block filling mining method. The specific implementation methods are as follows:

[0021] (1) Divide the entire mining area into multiple areas, such as figure 1 , 4 As shown, eac...

Abstract

The invention discloses a pillar pre-isolation sublevel stick-filling mining method and an ore body therefor. The pillar pre-isolation sublevel stick-filling mining method comprises the following steps of 1, dividing the whole mining area into multiple zones, dividing each one of the zones into a step-I stick chamber, a step-III stick pillar, a step-II stick chamber and a step-IV stick pillar orderly arranged along an ore growth direction, and 2, orderly carrying out stoping on the step-I stick chamber, the step-II stick chamber, the step-III stick pillar and the step-IV stick pillar, wherein the same-step stick stopes in all the zones are stoped simultaneously. The pillar pre-isolation sublevel stick-filling mining method has the advantages of low mining cost and high production efficiency.

Description

technical field [0001] The present invention relates to a mining method and an ore body, in particular to an ore pillar pre-segregation segmental strip filling mining which is suitable for mining an ore body that is not stable and the surface does not allow subsidence of a gently inclined or steeply inclined thick metal ore body Law. Background technique [0002] When mining extremely unstable, thick, large and low-grade ore bodies, the caving method is generally used for mining. However, caving mining will cause surface subsidence and affect sustainable development. Especially when mining under farmland, the surface subsidence is not allowed, so filling mining is required mining method, filling mining method has high cost and low production efficiency. Contents of the invention [0003] The object of the present invention is to provide a mining method for pre-isolation of ore pillars, segmentation and block filling and an ore body. The mining method has low mining cost a...
