1.花色品种及其变化,因为石材的应用价值主要是由它的装饰性能(颜色花纹)所决定的;2.构造、节理裂隙发育程度,这是决定矿山开采荒料率的关键因素,荒料块度过小,荒料率过低,就失去了开采价值;3.覆盖层和风化层的厚度,这是决定矿山投资和开采成本、影响经济效益的重要条件;4.影响石材质量的色线色斑分布及放射性强度,这也是影响其装饰性能及市场价值的重要因素;5.石材矿石的物理性能和加 1. Variety and variety of color, because the application value of stone is mainly determined by its decorative performance (color pattern); 2. Construct and join the degree of fracture development, which is the key factor that determines the rate of block mining, The block size is too small, the rate of block material is too low, it lost the value of mining; 3 cover and weathering layer thickness, which is to determine the mine investment and mining costs, affecting economic conditions, an important condition; 4. Stain distribution and radioactive intensity, which is also an important factor affecting the decorative performance and market value; 5. The physical properties of stone ore plus
