| Abstract: | Failure events which could cause faults of auxiliary hydraulic systerms of electrical haulage shearer were collected for reducing faults of auxiliary hydraulic systerms of electrical haulage shearer and ensuring sustaining and high efficency of producing in coal mine and working safty of operator.Fault tree analysis methord of mining safty engineering was used to analyse fault tree of which and find primery and subsidiary of influence factors of this fault.Preventive measures of this fault were put forward accordingly. |
| Keywords: | electrical haulage shearer auxiliary hydraulic system fault tree analysis |
