望田煤矿开采11号、13号、13下号煤层。11号煤层、13号煤层一采区采用综采工艺，13号煤层二、三采区采用综采放顶煤工艺，技术上可行、经济上是合理，有利于实现高产高效安全生产。工作面布置在首采区内，采区内采用前进式开采，回采工作面采用后退式回采，采区回采率可达75%。
望田煤礦開採11號、13號、13下號煤層。11號煤層、13號煤層一採區採用綜採工藝，13號煤層二、三採區採用綜採放頂煤工藝，技術上可行、經濟上是閤理，有利于實現高產高效安全生產。工作麵佈置在首採區內，採區內採用前進式開採，迴採工作麵採用後退式迴採，採區迴採率可達75%。
망전매광개채11호、13호、13하호매층。11호매층、13호매층일채구채용종채공예，13호매층이、삼채구채용종채방정매공예，기술상가행、경제상시합리，유리우실현고산고효안전생산。공작면포치재수채구내，채구내채용전진식개채，회채공작면채용후퇴식회채，채구회채솔가체75%。
In Wangtian Mine, No.11, No.13, and No.13b seams could be mined. The first mining areas of No.11 and No.13 could use fully-mechanized mining technology, while for the second and third mining areas of No.13, top coal fully-mechanized mining could be used, feasible in technology and reasonable in economy, which could realized the safe and efficient production. When working face is in the first mining area, advancing mining is adopted in the mining area and retreat mining in the caving face, with recovery rate of 75%.
