为预防井下采空区引发的矿山灾害，设计并建立了赣中钨矿井下废石充填系统。充填系统包括侧卸式矿车输送、机车运输、电耙倒运及充填井巷工程。2年来，共有8个采空区的32.2万 m3采空区得到有效充填，工程应用结果表明，废石充填率为60％～70％，能有效预防岩移、岩爆及地表沉陷等灾害；此外，充填系统每年可节约废石提升与运输费用600万元／a，并减少了地表废石堆场体积。
為預防井下採空區引髮的礦山災害，設計併建立瞭贛中鎢礦井下廢石充填繫統。充填繫統包括側卸式礦車輸送、機車運輸、電耙倒運及充填井巷工程。2年來，共有8箇採空區的32.2萬 m3採空區得到有效充填，工程應用結果錶明，廢石充填率為60％～70％，能有效預防巖移、巖爆及地錶沉陷等災害；此外，充填繫統每年可節約廢石提升與運輸費用600萬元／a，併減少瞭地錶廢石堆場體積。

To control potential mining hazards induced by underground goafs,the waste rock backfill sys-tem was designed and constructed in GanZhong Tungsten Mine.The system includes conveying equip-ments of tramcars,rock transfer by electric rakes,haulage network and mining workings.Total volume of 322 000 m3 in eight gobs is efficiently backfilled with waste rocks in the past two years.Field effects indi-cate that backfill rate is 60% ~70%,which is applicable to control potential hazards such as rock move-ment,rock burst and surface subsidence.Additionally,backfill construction reduces the annual prices of rock lift and transportation by six million yuan every year,which further lowered the land use of surface dumping.
