A grounding module comprises a module body and is characterized in that the formula of the grounding module basically comprises the following components in parts by weight: 13-17 parts of coke powder, 1.5-8 parts of cement, and 0.3-5 parts of graphite powder. The formula of the grounding module further comprises 0.3-5 parts of ion releasing agent. The grounding module has the advantages that the grounding module adopts natural nonmetallic mineral materials which have excellent conductivity and soil compatibility as conducting medium of the grounding module, conductivity of the grounding module is not affected by seasons, so that stable ground resistance is provided, besides, due to the nonmetallic mineral materials, a low resistance zone which is gentle in variation is formed between metal and soil which have huge difference in resistivity, step voltage and contact voltage are lowered, probability of occurrence of ground potential counterattack is reduced, moreover, by matching an ion releaser, electrolyte can durably permeate into the soil in a high concentration mode, the goal that ground resistance can be rapidly lowered is achieved, and characteristics of the grounding module such as density, corrosion resistance, conductivity, compressive strength are enhanced.
