注浆加固技术在松软煤层探放水中的应用

Grouting Reinforcement Technology in Soft Coal Seam Drain

老空积水是危害矿井安全生产的重大隐患之一,采取适当的方法进行探放水是保证矿井生产安全的重点。通过煤体注浆加固技术大大提高了煤体的强度和完整性,有效地解决了松软煤层探放水过程中钻孔易塌孔、冲孔、孔口管无法锚固和煤柱易冲垮等难题,为松软岩层中探放老空水积累了经验。

The old empty water is one of the major hidden danger of damage to the mine safety production, drain is to ensure that the ap- propriate methods for the key point of the mine production safety. Through grouting reinforcement technique has greatly increased the coal of coal strength and integrity, effectively solve the soft coal seam in the process of the drain hole hole collapse, punching and orifice tube cannot anchor and easy to burst, coal pillar for soft rock strata of old empty water accumulated experience.
