Mine is too ancient geological ore mixed granite and granite porphyry, ores major components of SiO2, accounting for 76.54%, Al2O312.56%, Qianhui, the fine-grained gray granite block change crystal structure, long-ramp of 27 -- 36 percent, longer-35-42 percent, 20-29 percent quartz, rock weighing 2.6 T/m3, hardness of 5.9-6.3 degrees, the porosity of 0.62-1.03 percent, compressive 1670-1931 kg/cm2, bending 141-167 kg / cm2, ore reserves 2000 investigation Grade D geological reserves 10.02 million cubic meters, designed for the use of reserves of 7.99 million cubic meters; mining area of 0.4 cubic kilometres, the highest elevation of 151 meters, the minimum 56 meters, hilly slope, with perennial Shuixi, More sparse vegetation.

矿山地质矿体属太古代混合花岗岩及花岗斑岩，矿石主要成分SiO2，占76.54%，Al2O312.56%，浅灰，灰白色的细粒花岗变晶块状构造，斜长石含量27-36%，更长石35-42%，石英20-29%，岩石体重2.6T/m3，硬度5.9-6.3度，孔隙度0.62-1.03%，抗压1670-1931kg/cm2，抗折141-167kg/cm2，矿石储量2000勘测D级地质储量1002万立方米，设计利用储量为799万立方米；矿区面积0.4立方千米，最高海拔为151米，最低56米，丘陵缓坡，无常年水溪，植被较稀疏。

By use of the Fischer-Tropsch reaction in a C-H-O system, we discussed the relationships between inorganic CO〓 and some physical chemistry conditions, such as Oxygen flee degree , temperature, pressure, other objects consistency and catalyzer. a when T=200K～2000K, if f〓＞0, the reaction of generating CO〓 will be dominant, CH〓 hardily exists; b when T＞1000K, CH〓 is not propitious to exist, carbon in system almost exists in form of CO〓; c the more pressure, the more CO〓 is propitious to exist; d the more consistency of CO, O〓 and H〓O, the more CO〓 is propitious to exist, the more consistency of H〓, the more CH〓 is propitious to exist.

依据C-H-O体系费托反应的简化模型，讨论了氧逸度、温度、压强、其它物质浓度、催化剂等物理化学条件对无机成因CO〓生成的影响，从理论上讨论了在地质环境中，无机成因CO〓存在的物理化学条件：1在T＝200K～2000K的温度范围内，体系中一旦氧逸度＞0，生成CO〓的反应将占绝对优势，CH〓几乎不可能存在；2T＞1000K时，不利于CH〓形成，使体系中的碳主要以CO〓的形式存在；3体系压强越大，越有利于CO〓的形成；4反应物CO、O〓、H〓O的浓度越高，越有利与CO〓的存在，H〓的浓度高有利于CH〓的形成。5地质成藏作用可以经历很长的地质年代，这足以补偿矿物岩石中的Ni、Mo、Fe、Co、Ru等催化性能的降低及其它动力学条件的不足，使得费托反应可能发生，从而生成无机成因的CO〓和烃类。
