采矿方法的改进途径是多种多样的。本文所讨论的采矿方法,其矿体具有以下特点:围岩一般由不稳固至极不稳固,矿石一般由中稳至稳固;矿体倾角一般为10~30°左右;矿体厚度一般为4.0~12米,少数地段有3.0米以下或12米以上厚度。从国内矿山来看,如铜、锡、锑、铁以及非金属矿都有此类矿床;从云南地区来看,个旧松树脚锡矿和牟定铜矿清水河矿床都有此类矿体。此类矿体滇中牟定清水河矿床最为典型。该矿床赋存于下白恶系落苴美组郝家河段浅色砂、页、砾岩中。矿体呈似层状
There are a variety of ways to improve mining methods. The orebody discussed in this article has the following features: The surrounding rock is generally unstable and extremely unstable, and the ore is generally stable from stable to stable. The orebody dip angle is generally about 10 ~ 30 °, and the orebody thickness is generally 4.0 ~ 12 meters, a few lots have 3.0 meters below or 12 meters above the thickness. From the domestic mines, such as copper, tin, antimony, iron and non-metallic mineral deposits have such deposits; from the Yunnan region, Gejiu pine foot tin mines and Mouding Copper Mine Qingshuihe deposits have such ore body. Such ore deposits in central Yunnan Mouding Qingshuihe most typical. The deposit occurs in the lower part of the white-line system of the United States Haojiahe pale sand, pages, conglomerates. Ore body is layered
