The Application of New High-Strength Polyester Fiber Flexible Net for the End Coal Mining Through

Abstract:

Shendong mining area hanging nets adopted metal mesh material in the traditional through of fully mechanized coal face. Whose defects were the high cost of materials, process cumbersome, great labor intensity and time consuming. Therefore, new high-strength polyester fiber flexible mesh material was introduced. Its main advantages are: light weight, tensile resistance and drag force strong, flame-retardant and anti-static, low cost, simple process, high efficiency, coal cutting speed. The construction technology process in detail were designed which contained flexible network transported, fixed, dropped and raised. The project was implemented in Shigetai Coal at the end of No.12401 mining face. Results show that from working face mounting network to smoothly through with only 40 hours, compared with the traditional metal net can save 44 hours and cost 480000 yuan.
