摘　　要：采用И Г Д．ＡＨ法对大洋多金属锰结核的普氏系数进行了测定，并与无烟块煤的普氏系数进行了对比实验，发现它们的普氏系数非常接近，因而用煤替代大洋多金属结核进行破碎试验的可行性。同时根据锰结核的破碎强度和物理化学特性确定了用齿辊破碎方式进行破碎的实验方法。The testing on protodrakonov scale of hardness of the oceanic multi-mend core using И ГД. AH method is stated the experiments are made for comparison with the protodrakonov hardness of bituminous, it is found through the test that their baldness are similar Therefore the feasibility of conducting crushing test using coal other than the oceanic multi-metal nodule is confirmed. In addition, according to the crushing strength and physical, chemical properties of manganese nodule, the testing method for crushing using toothed roll crusher is established.
