摘 要:为进一步提高充填采煤效率,保证固体充填质量的一致性,提出采用固体充填自动化技术,设计研发了固体充填自动化控制系统。给出了自动控制策略和方法,包括充填液压支架推力与密实充填率之间数学关系,充填体自由度对充填采煤工作的影响以及充填采煤的时空特性,深入剖析了自动化充填采煤与控制工作面顶板上覆岩层的运移规律。同时,系统中液压支架自动控制流程、传感器布控原理以及系统控制模式实现了现场工业应用。结果表明:充填效率和推进速度均提升49%左右,劳动强度和充填成本大幅下降,充填效果明显提高,有力推动了固体充填采煤的科学发展。In order to further improve a backfill coal mining efficiency and to ensure a consistency of the solid backfill quality,an automatic technology of the solid backfill was provided and an automatic control system of the solid backfill was designed and developed. An automatic control tactics and method were provided,including the mathematical relationship between the thrust of the backfill powered support and the dense backfill rate,the backfill freedom affected to the backfill mining operation and the space- time characteristics of the backfill coal mining. The paper in detail analyzed the automatic backfill coal mining and the migration law to control the overburden strata above roof of coal mining face. Meanwhile,the automatic control procedure of the powered support in the system,the distribution and control principle of the sensors and the system control mode were realized in the site industrial applications. The results showed that the backfill efficiency and pushing forward speed were both improved about 49%,the labor intensity and backfill cost were highly reduced,the backfill effect was obviously improved and the scientific development of the solid backfill coal mining was powerfully promoted.
