摘要
针对薛虎沟煤业2-103工作面煤层上分层煤早期受小窑破坏开采较为严重,小窑资料不明,复采火灾隐患严重等问题,结合工作面实际揭露情况,分析了复采工作面煤层自燃危险因素,通过采取堵漏风、预测预报、预防性注氮、喷洒阻化剂等综合防灭火措施,有效保障了2-103复采工作面的安全回采,并为今后其他同类复采工作面煤炭自燃的防治工作提供了借鉴。
Xuehugou coal mine used to be operated by some private entity,due to random mining and the lack of specific geological data,the current No. 2-103 mining face which is just under the former mining area faces the hidden risk of fire and spontaneous combustion. The paper analyzes the factors of spontaneous combustion with combination of the emerged problems,comprehensive fire prevention measures are adopted,namely,air leaking stoppage,forecasting,preventive nitrogen injection and resistance agent spraying,so to guarantee the safety during remining in the No. 2-103 work face,the experience is of reference for similar cases.
