Description
Technical field
The utility model belongs under the coal mine opens up equipment technical field, particularly is applicable to the rotatable flexible cutting means of the comprehensive mechanized rock roadway tunneling machine group of large, medium and small type coal mine down-hole rock tunnel mechanization developing operation.
Background technology
Open up equipment technical field under coal mine, the traditional handicraft mode of all kinds of mine stone driftings is mainly the big gun pick, and support pattern is anchor pole, anchor cable, joist, anchor net combination supporting.The big gun pick is the perforating of gas leg type air drill, powder charge, blows out; Blow out the spoil that falls, adopt again rock rake to transport work plane by hand breaking first; After the work plane spoil cleans out, use the monomer air drill to carry out bolting and rope support.Mainly there is following problem in this stone drifting job practices of blowing out:
1, the tunnelling section is little: excavated section is generally at 15m
2About, when head-room surpasses 2m, must just can carry out top-assisting anchor rod and anchor cable construction by scaffolding;
2, speed of application is slow: when the construction section surpasses the 2m height, must build and remove scaffold, need a large amount of time; Just necessary hand breaking had spent a large amount of time, otherwise can destroy main delivery system when the spoil width surpassed 300mm.The integral construction advance of working cycle is low, all in 2m;
3, efficient is low: owing to perforating, broken spoil, bolting and rope support are manual work, the constructor is many, causes operating efficiency low;
4, safety factor is low: the constructor is staggered operation in the high-altitude, and the job safety environment is poor.Perforating, broken spoil, bolting and rope support be operation under the sky top all, exists potential safety hazard;
