Research on hidden disaster factors and prevention measures in Pingdingshan No.11 Coal Mine
Coal mine safety production is an important part of industrial production,and the safety hazard is the direct cause of coal mine accidents.This paper conducted a detailed study on the hidden disaster factors such as structural,geological,and engineering factors by means of production disclosure,geophysical exploration,drilling,underground observation,analysis,and calculation.The main hidden disaster factors were determined,and targeted prevention measures were put forward according to the situation and characteristics of dis-aster causing factors.The research shows that the main hidden disaster factors in No.11 Coal Mine are fault,limestone confined water,goaf water and gas,which threaten the safety production of the mine.It is necessary to establish a ledger based on different geological factors,classify management,and reasonably arrange disaster causing plans to better serve the safety production of the mine.
