Ground extraction of coal-bed methane (CBM) is considered as an effective way to reduce coal seam gas content and warrant coal mine safety. Taking the 5th East Panel at Sihe coal mine in Jincheng as an example, based on the reservoir simulation data in 14 inspection wells and 141 production wells, the ground CBM extraction effect has been assessed. Firstly, by comparing the in-situ gas content and present gas content from 14 inspection wells, the degassing effect was evaluated. Secondly, by conducting the reservoir history matching and the simulation of 141 production wells, the future degassing effect was predicted. The results show that the degassing effect of the ground gas drainage is obvious at the 5th East Panel in Sihe Coal Mine after the 7-year ground gas extraction. The present gas content drops to 10.51 m3/t from the in-situ gas content of 23 m3/t and the descending range averages 55%; Using reservoir simulation, the residual gas contents are 10.07, 7.31 and 4.35 m3/t after 7-year, 10-year and 15-year drainage respectively, and the descending range are 57%, 69% and 82% respectively.

In order to find out the feasible co-layer drainage between No. 3 and No. 15 coal reservoir in the southern Qinshui Basin, according to the producing gas characteristics of CBM vertical wells, the factors of the height of the critical production gas, the grades of reservoir pressure, the ability of supply for liquid and the permeability are the main controlling factors to influence the joint drainage, and the suitable conditions about the joint drainage was gained. According to the the exploration data in Sihe block, the main controlling factors were analyzed. The results show that various controlling factors are suitable in Sihe block. The drainage experiment validates that the theory is reliable.

To liberate the unexploited coal resources beneath buildings, a new kind of super-high-water material can be used as the filling material in goaf, whose water volume and water cement ratio can be reached to 97% and 11:1, respectively. Based on the basic properties of super-high-water materials, bag-type filling mining method is proposed. In this technology, the mixed slurry of super-high-water materials are injected into the filling bags which have been erected in goaf in advance, and then the solidified filling bodies can slow down the surface subsidence effectively by controlling overlying strata activity. The technology has been applied successfully in the experimental filling face in Taoyi Coal Mine. The application shows that the super-high-water material is a kind of goaf filling material with good performance in a wet, cold and closed underground environment, and the technology is an advanced green mining method to liberate unexploited coal seams under buildings, with the obvious advantages of simple filling process, low initial investment, high mechanization degree, convenient practical operation, strong adaptability to the geological conditions and mining technologies in coal mines, and so on.

The beam pump unit is widely used in Coal-bed methane(CBM) wells for mining of CBM. In the past few years, the main electrical drive system applied in beam pump unit for CBM wells is electromagnetic speed motor. Aiming at drawbacks existed in electromagnetic speed system such as high energy consumption and low system efficiency, we propose a variable frequency speed system based on vector control technology for CBM wells. This paper analyzes and builds the mathematical model of the load torque of the beam pump and the mathematical model of AC drives control system of the beam pump using vector control technology. Based on the above analysis, we further set up the whole simulation model of the vector control system of beam pump for CBM wells. The simulation results show that the control system can automatically adjust the real-time dynamic torque motor current, in order to match the output torque of the motor with the load characteristics of the beam pump, and prove to having an excellent performance of speed control. The field experiment data verify that compared with the electromagnetic speed system, the proposed control method using in CBM wells can definitely improve the system efficiency and reduce the energy consumption. © 2015 IEEE.

Crack closing in brittle rock under compression plays an important role in rock failure, and the corresponding engineering, such as coal mining, civil engineering, etc. In this paper, we formulate the circumferential stress and the corresponding initial fracture point around flattening elliptical hole under compression using linear elastic fracture mechanics theory. When considering the expansion of closed crack under pressure, we introduced an effective friction coefficient to obtain the advantages derived crack angle of the crack surface which have inversely proportional relationship, then RFPA is used to simulate the rock samples with prefracture. The results show that: (1) With the axial displacement exerting, the crack occurred closure, the end of the rock fracture produced a curved path expansion at the same time. (2) The plane of weakness occurred fracture firstly that lead to the weakness plane through and then formed to be cracks. (3) The final destruction face of the rock is approximately a forty-five slip-line. We can draw the following conclusions: The numerical study shows the final failure mode of the rock display compression and shear failure, crack angles make the differences of initial cracking angle, the crack propagation mode and its ultimate failure mode are similar, have no effect the carrying capacity. The research provides a reference to coal mining engineering, as roadway supporting, roof failure, etc. © 2013, EJGE.

For the purpose of exploring"two-zone" height of soft overlying strata working face, taking Shenhua Ningxia Coal Industry Group Hongliu Coal Mine 1121woking face as an example, three kind of technological method to explore "two-zone" height were used. Three method were loses of drilling fluid measuring, borehole wall observing by colour TV and transient electromagnetic method(TEM) geophysical exploration. On condition that the coal mining technology is fully-mechanized and fully-seam caving mining and the seam is slightly-tilt, thick and the overlying strata is soft, comprehensive research show that the caving height is 8.55 times the thickness of the coal seam, and the height of permeable fracture zone is 12.51 times the thickness of the coal seam. Three techniques have great difference in accuracy though they are the direct observation. Authors conclude that borehole colour TV is the best, loses of drilling fluid measuring is next, TEM geophysical exploration is the worst.

Focused on the characteristic of coal seam in southern Qinshui Basin and analysis on the process and difference of production from one group well, the conclusions are shown that: in different group single-well, the gas production has a large change, production effect has obvious difference, water production capacity is also difference; in the process of CBM production, in order to avoid sand is brought out and compression-sensitivity, the production intensity and institutional adjustment are not be too large and frequent. Using different working system in different stages of CBM production, in the early stage is mainly drainage, the core of working system is controlled by the fluid level; in the medium-late stage is mainly gas production, the core of working system is controlled by the casing pressure (bottom hole flowing pressure). In the process of CBM production, on the premise of keeping a certain back pressure and ensuring coal seam security, as possible as decreases casing pressure to product in order to decrease the average pressure of coal seam, enlarge the range of CBM adsorption and get high gas production.
