摘要:
为了探究布尔台煤矿回采工作面瓦斯涌出主控因素及其治理措施,以42201回采工作面为例,采用单元法现场实测了工作面瓦斯涌出情况,并分析了其受开采强度、风量、煤层瓦斯含量、工作面来压变化、气候条件等相关参数的影响规律。研究结果表明:布尔台煤矿42201回采工作面的主要瓦斯涌出来源为煤壁和落煤瓦斯涌出;矿山压力显现和来压时,工作面绝对瓦斯涌出量有较为明显的异常变化;开采强度的变化趋势和上隅角瓦斯浓度异常变化的趋势是一致的;对比发现,地面大气压力对工作面瓦斯涌出的影响程度远小于开采强度。针对布尔台煤矿的特点,提出了“顶板定向长钻孔分段水力压裂强制放顶和联巷插管或煤柱大直径钻孔桥接采空区的瓦斯抽采相结合”的瓦斯治理措施。现场应用发现:42201工作面最高来压强度由59.1 MPa降低至48.0 MPa,上隅角瓦斯抽采量为2.70~3.79 m3/min,平均为3.25 m3/min,占总的瓦斯涌出量的比例为62.65%~69.16%。
Abstract:
In order to study the main controlling factors and control measures of gas emission in the mining face of Buertai coal mine, taking the 42201 working face as an example, the gas emission situation of the working face were measured onsite by using the unit method, and the influence laws of relevant parameters such as mining intensity, air volume, gas content of coal seam, weighting change of working surface and climatic conditions on the gas emission were analyzed. The results showed that the main sources of gas emission in 42201 mining face of Buertai coal mine were the coal wall and coal falling. When the mine pressure appeared and the weighting came, the absolute gas emission quantity of the working face had obvious abnormal change. The variation trend of mining intensity was consistent with the abnormal change of gas concentration at upper corner. The comparison showed that the influence of the ground atmospheric pressure on the gas emission of working surface was much less than that of mining intensity. Aiming at the characteristics of Buertai coal mine, the gas control measures of combining the topplate directional long borehole segmental hydraulic fracturing forced caving with the gas extraction of connecting lane pipe laying or coal pillar largediameter borehole bridging goaf were proposed. The field application showed that the maximum weighting strength of 42201 working face reduced from 59.1 MPa to 48.0 MPa, and the gas extraction volume of upper corner was 2.70-3.79 m3/min, with an average of 3.25 m3/min, accounting for 62.65%-69.16% of the total gas emission.
