進行試驗的鑛床是急傾斜薄矿脈,其厚度从數公分起到30～40公分不等。矿石及圍岩係穩定性花崗岩,其普氏硬度係數為12～14。鑛床鑛石的体重為2.65噸/立方公尺。鑛石与圍岩接觸不明顯,有時並有地質破壞现象。鑛脈不論沿傾斜或沿走向都很穩定。在開採对象中,除鑛脈外,尚有1.5～3公尺厚的岩脈,該岩脈內含有若干細鑛脈,其金屬品位很高。在該鑛山以留鑛採鑛法作為開採薄鑛脈的主要方法,其參數是:中段高50公尺,鑛塊走向長度40～60公尺,開採鑛脈時採矿场寬度為1～1.3公尺,開採岩脈時採鑛場寬度為1.5～3公尺。
The deposits tested are steeply dipping thin veins whose thickness varies from several centimeters to 30-40 centimeters. Ore and rock stability of granite, the Platts hardness coefficient of 12 ~ 14. Ore ore weight of 2.65 tons / cubic meter. Ore and rock contact is not obvious, and sometimes there is the phenomenon of geological damage. The veins are stable either along the slope or along the strike. In the mining object, in addition to the mine, there are 1.5 to 3 meters thick dikes, the vein contains a number of fine veins, the metal grade is high. In this mine, the ore-retaining mining method is the main method for mining thin veins. The parameters are as follows: the mid-section height is 50 meters, the length of the ore block is 40-60 meters, the mining field width is 1 ~ 1.3 meters, when mining dikes mining field width of 1.5 to 3 meters.
