对某深井煤矿不同深度的含硅藻泥岩进行了单轴无侧限抗压强度试验。通过分析试验数据可知,含硅藻泥岩的单轴无侧限抗压强度受温度、加载速率、含水率等因素影响,温度越低,加载速率越大,含水率越低,抗压强度越高。 Uniaxial unconfined compressive strength tests were carried out on diatomite mudstone with different depths in a deep coal mine. Through the analysis of experimental data, it can be seen that the uniaxial unconfined compressive strength of diatom-bearing mudstone is affected by temperature, loading rate and moisture content. The lower the temperature, the higher the loading rate, the lower the moisture content and the higher the compressive strength .
