| 1 | Ground response to high horizontal stresses during longwall retreat and its implications for longwall headgate support显示文摘Roof falls in longwall headgate can occur when weak roof and high horizontal stress are present. To prevent roof falls in the headgate under high horizontal stress, it is important to understand the ground response to high horizontal stress in the longwall headgate and the requirements for supplemental roof support. In this study, a longwall headgate under high horizontal stress was instrumented to monitor stress change in the pillars, deformations in the roof, and load in the cable bolts. The conditions in the headgate were monitored for about six months as the longwall face passed by the instrumented site.The roof behavior in the headgate near the face was carefully observed during longwall retreat.Numerical modeling was performed to correlate the modeling results with underground observation and instrumentation data and to quantify the effect of high horizontal stress on roof stability in the longwall headgate. This paper discusses roof support requirements in the longwall headgate under high horizontal stress in regard to the pattern of supplemental cable bolts and the critical locations where additional supplemental support is necessary. | Peter Zhang Dave Gearhart Mark Van Dyke Daniel Su Essie Esterhuizen Berk Tulu | 2019 | International Journal of Mining Science and Technology2019，29，1： | 6 |
| 2 | Inflammatory bowel disease associated neoplasia:Asurgeon's perspective显示文摘Inflammatory bowel disease(IBD) is associated with increased risk of colorectal cancer(CRC). The risk is known to increase with longer duration of the disease, family history of CRC, and history of primary sclerosing cholangitis. The diagnosis of the neoplastic changes associated with IBD is difficult owing to the heterogeneous endoscopic appearance and interobserver variability of the pathological diagnosis. Screening and surveillance guidelines have been established which aim for early detection of neoplasia. Several surgical options are available for the treatment of IBD-associated neoplasia. Patients' morbidities, risk factors for CRC, degree and the extent of neoplasia must be considered in choosing the surgical treatment. A multidisciplinary team including the surgeon, gastroenterologist, pathologist, and the patient who has a clear understanding of the nature of their disease is needed to optimize outcomes. | Azah A Althumairi Mark G Lazarev Susan L Gearhart | 2016 | World Journal of Gastroenterology2016，22，3： | 4 |
