%X A three-dimensional computational model is applied to analyze the stability of rock-bolting and shotcreting support in the floor haulage roadway. The mining sequence effects in different working faces on stability of floor haulage roadway in high tectonic stress field in Fangezhuang Coal Mine are discussed. The main factor causing destruction of roadway in tectonic stress field is found to be the high tensile strain, which appears after the coal seam above haulage roadway is mined. In addition,the key principle of laying floor haulage roadway in high-level stress field is proposed in this paper to keep pillars above the haulage roadway unmined. In this way, the obvious influences of high abutment pressure induced by coal mining can be alleviated or avoided for the roadway is at nearly equal pressure on both directions. It is proved by engineering practices in Fangezhuang Coal Mine of Kailuan Group Limited Liability Company that the key principle is capable of reducing maintenance of haulage roadway in service and maintaining the stability of the roadway.
