Research Progress and Development Trend of Mining Technology under Building

Experimental studies on coal mining under buildings in China started since 60's of last century successively in Benxi,Hebi,Fushun,Zaozhuang,Fengfeng,Jiaohe and so on,and successful experience and precious monitoring material had been obtained.Based on full literature search and comprehensive analysis,the current status is described from the mining technologies of coordinated mining,backfill mining,partial strip mining,and filling the collapsed cavities in over lying strata.The developing trend is prospected.It is considered that filling the collapsed cavities in over lying strata,filling with gangue,partial strip mining,and to reconstruct the anti-distortion room on quondam place would be further developed in future in China.
