阳大铁路采空区路基处理技术研究

Introduction To the Goaf Treatment of Yang Da Railway Subgrade

山西阳泉是硫铁矿资源大市,硫铁矿开采后形成了很多的采空区,阳大铁路采空区治理能对铁路采空区治理有一定的参考价值。钻孔、注浆、检测是采空区处理的程序,采空区种类多样,根据实际,及时改进方法,本文主要谈论硫铁矿采空区的钻孔、注浆技术,特别是依据取芯的结果对于地层的分析,制浆的方法有重要描述,其中的一些先进经验值得推广,对于规范铁路采空区治理技术起到借鉴作用。

The city of Yangquan is large pyrite resources inshanxi. Alot of mined- out area is formed after pyrite mine, Thegoaf treatment of Yang Da railway subgrade has the certain reference value to similar projects. Main process of the goaf treatmenincludes drilling, grouting, detection, etc According to differentype of mined - out area,Construction process should be adjusted appropriately. This paper mainly talk about pyrite mine goagovernance for different layer, being used for goaf governance odifferent of railway technology..
