Shock capacity of the “southern” polymetallic deposit in Primor'ye
- 13 Downloads
1. The tendency of the rock mass of the Southern Deposit to mine shocks is a result of leftward-shifting tectonic dislocations of the earth's core, which are characteristic for Primor'ye, and which were caused by the following: recrystallization of rocks as a result of their contact metamorphism, effected by deep magmatic injections formed in the area of separations in the sedimentary cover; an accumulation of potential tectonic-strain energy in the body of the intrusion; and, discrete settlement of the underworked structural blocks in the worked space of the deposit, which occurs along the planes of tectonic faults.
2. The development of mine shocks in the deposit is basically the result of activation of the neotectonic mobility of disjunctive faults making up the Eldorado fault zone, and definable working of the ore veins.
3. Seasonal influxes of surface water to mine workings increases the number of manifestations of mine pressure in dynamic form.
