The invention discloses a mineral hardness detection device and a detection method thereof, a coal mining machine and a mineral classification method, which can make a mineral sample into a detection sample, and obtain a mineral firmness coefficient by detecting the ultimate pressure of the detection sample, thereby realizing accurate and automatic detection of mineral hardness. The mineral hardness detection device comprises a moving trolley, a sample preparation assembly, a detection assembly and a control and calculation assembly. The sample preparation assembly comprises a hollow drill (19), a drilling machine driver (16), a lifting mechanism and a fixing mechanism. The detection assembly is used for extruding the detection sample to detect the pressure on the detection sample and transmitting the pressure on the detection sample to the control and calculation assembly. And the control and calculation assembly is electrically connected with the detection assembly and is used for obtaining the ultimate pressure of the detection sample according to the pressure of the detection sample, calculating the uniaxial compressive strength of the detection sample and converting the uniaxial compressive strength into a mineral firmness coefficient for display.

    本发明公开了一种矿物硬度检测装置及其检测方法、采煤机、矿物分类方法,能够将矿物样品制作为检测样品,并通过检测检测样品的极限压力得到矿物坚固性系数,从而实现对矿物硬度的精确自动检测。该矿物硬度检测装置包括移动小车、制样组件、检测组件以及控制和计算组件。制样组件包括空心钻(19)、钻机驱动机(16)、升降机构和固定机构。检测组件用于对检测样品进行挤压以检测对检测样品的压力,并将对检测样品的压力传输至控制和计算组件。控制和计算组件与检测组件电连接,用于根据对检测样品的压力得到检测样品的极限压力,并计算出检测样品的单轴抗压强度后转换为矿物坚固性系数进行显示。
