To ascertain the adsorption characteristics of coal reservoirs in the Ewirgol mining area of the western margin of Turpan-Hami Basin, this paper systematically collected and sorted the coal rock and coal quality data and isothermal adsorption data and analyzed it. The adsorption characteristics of coal reservoir were clarified and the relationship between the depth, coal rank, coal microscopic components and coal quality with adsorption characteristics were analyzed. The research shows that the Langmuir volume of coal reservoirs in the study area ranges from 14.37 m3/t to 27.84 m3/t, with an average of 25.07 m3/t. The Langmuir pressure falls between 1.14 MPa and 3.45 MPa, with an average of 1.77 MPa. Under the combined action of temperature, pressure, porosity and other factors, the adsorption capacity of coal reservoirs exhibit a positive correlation between with buried depth and a “high-low-high” change law with the increase of coal rank. The adsorption capacity of coal reservoir increases and decreases with the increasing vitrinite content and inertinite content, respectively. The greater the moisture and ash yield in the coal, the weaker the adsorption capacity of coal. On the whole, the adsorption capacity of the coal reservoir in the study area is strong and is evidently dependent on the burial depth, and the deep coal reservoir has a good potential of CBM resources.

Hoisting work usually involves heavy lifting equipment with high risk and high requirements for operator. The training would be"ifgurative"theory if only talked in the classroom, which can not effectively improve staff skills, but if practice training directly at the scene of the hoisting is high risk and high cost, which is hard to be accepted by enterprise. Therefore, the article designs a set of simulation training facilities, fully simulates the hoisting ifeld training to employees.

阐述了不同煤阶煤层气富集规律,总结了中高煤阶沉积控藏、水动力控气、断裂控制的特征,并指出是否具有充足的气源补给和良好的封盖条件是低煤阶富集的关键.在煤层气地质资源量计算上虽然仍利用体积法,但随着煤层气勘探开发工作的进一步开展,详实的资源评价参数大大增加了计算结果的准确性,同时丰富可采资源量的研究方法,进一步提高了其结果的可靠性.结合我国煤层气资源分类分布结果,总结了我国煤层气资源整体上“南北分区、东西分带”的特征,即由东向西从相对富气带转变为相对贫气带,由北向南从压力类型区渐变为应力类型区,处于中间地带的华北、鄂尔多斯等盆地容易形成富集高产区.
