摘要
当前,矿井采掘接替紧张情况普遍存在,随着开采范围的逐步扩大、开采深度的不断增加,越来越受到瓦斯、煤尘、冲击地压、地温、地下水、采空区水等灾害的威胁与影响,其采掘接替紧张问题愈发突出。各煤炭企业,特别是地质构造复杂、极复杂,水文地质条件复杂、极复杂,煤(岩)与瓦斯突出,冲击地压严重矿井采掘接替更为紧张,严重制约安全生产和企业的可持续发展。
Currently,there are widespread tensions in mining excavation succession,and the problem becomes increasingly prominent due to more and more threats and influences on mining by disasters such as gas,coal dust,rock burst,ground temperature,groundwater,water in the goaf,etc. along with the gradual expansion of mining range and increasing depth of mining. Coal enterprises,especially those in places with complicated and extremely complicated geological structures,complicated and extremely complicated hydrogeological conditions,coal(rock) and gas outburst,severe excavation pressure,have more tensions in mining excavation succession,and thus the production safety and sustainable development of enterprises are severely restricted.
