比利矿开采的扁豆状硼酸盐矿体,主要由硼砂、硬硼钙石和基性硼钠钙石组成,顶部发现部分硼钠钙石。因基性硼钠钙石的抗压强度约为45兆帕,且晶体结构不同,很难切割回采,所以只开采有硬硼钙石。矿层厚度为46～53米,覆盖层为46～39、0米,矿层向东南倾斜20°～30°,沿倾斜延伸约1100米,沿走向约200米。
Billets mining billets borate ore body, mainly by the borax, hardonite and basic borosilicate composition, the top part of the discovery of sodium sodalite. Due to the basic boro-soda limestone compressive strength of about 45 MPa, and the crystal structure is different, it is difficult to cut back to mining, so only hard-boronite mining. The thickness of the ore layer is 46-53 meters with 46-39.0 meters of overburden. The ore layer is inclined to the southeast by 20-30 degrees, extends about 1100 meters along the slope, and runs along about 200 meters.
