Recently，It is a complete set of rapid anchor digging equipment jointly built by Railway Construction Heavy Industry and State Grid Energy Hami Coal and Electricity Co., Ltd.，Help Xinjiang Hami City Dananhu No.1 Coal Mine 1309 Working Face Return Air Roadway to Achieve Point-to-Point Precision Connection for the First Time，It marks that the 1309 working face of the mine has formed a complete ventilation and transportation system.，It lays a solid foundation for the continuation of mining and excavation.。

The coal mine roadway is connected

It is understood that，Dananhu No.1 Mine is the second one in Xinjiang to be approved by the state.，And the first ten-million-ton underground mine put into production。The production capacity of the mine is large、High degree of modernization，Among them, 1309 working face construction is the key project of Dananhu No.1 Mine this year.，The complete set of equipment for rapid excavation and anchoring of Railway Construction Heavy Industry, which undertook the task, was successfully launched at the construction site in May this year.。

Considering the tight construction period、The task is heavy、Difficulties such as safety and quality risks，In order to ensure the successful completion of the equipment tunneling task,，China Railway Construction Heavy Industries Co., Ltd. has organized technicians to go down the well for investigation for many times.，According to the soft rock floor、Complex geological conditions such as lateral wall and roof fall，Targeted and customized design of equipment，Anchor bolt advance support is loaded、Quick disassembly of drill pipe、Excavation and support balance operation、Chassis efficient traffic and other key technologies，And that construction adaptability is ensure.，And that construction efficiency is improve.，The excavation is realized、Branch、Efficient and coordinated operation of all links，It provides safety for the precise penetration of roadway.、Reliable equipment support。

Through a series of customized technical research，Finally, the equipment successfully overcame many difficulties.，Continuous improvement of tunneling efficiency，Created 731 meters of monthly excavation footage in Xinjiang mining area、Daily footage record of 38 meters。

The complete set of quick digging anchor equipment is assembled in the workshop.

It is reported that，Successful Ending of 1309 Working Face Tunneling Task in Dananhu No.1 Coal Mine，It is a cooperation between Railway Construction Heavy Industry and State Grid Energy.、Successful practice of close cooperation，Effectively cracked the mining、Digging out the key problem of imbalance，It has laid a good foundation for the rapid excavation of mine under complex conditions.。
