Number of sensors is at least one, and multiple sensors can be monitored to material bed simultaneously；
2) when any group of range measurement L in two sensors is less than 0, the sensor degradation is represented；If two biographies
It is the measurement result with two smaller values of sensor measurement when the measurement result of sensor is both greater than 0；
3) angle of repose according to material sets 3 alarm distance value A1、A2、A3, and A1>A2>A3；And according to 3 alarming values
Corresponding warning device, preferably indicator lamp are set, wherein,
Work as L>A1When, current feeding face is in home, and indicator lamp reminds this layer of material extracting operation can to move on；
Work as A1<L<A2When, near optimum position, indicator lamp reminds this layer of material extracting operation can to stop for current feeding face position
Only；
Work as A2<L<A3When, current feeding face position has approached landslide danger zone, and indicator lamp reminds this layer of material extracting operation to answer
Stop immediately；
Work as L<A3When, current feeding face position closely caves in danger zone, and indicator lamp sends warning reminding；
4) controller is automatically stopped the revolution of bucket wheel reclaimer arm support and elevating movement, stops bucket wheel reclaimer advance fortune out of shape
It is dynamic
5) this guard method is additionally provided with function of shielding, and when function of shielding is opened, this method cannot be automatically stopped bucket wheel and take
The revolution of material horn frame, elevating movement, and stop bucket wheel reclaimer advance traveling function, only with prompting and warning function.
