Development of Support Plan and Operation Scheme for Semimechanized Longwall Face of Coal Seam 10T, Nam Khe Tam Mine – 86 Company, Dong Bac Corporation

Support plans and operation schemes of mine faces are critical technical documents inunderground coal mining management. The development and selection of a reasonable support plan andoperation scheme of the face are complicated because they involve many factors. In specific miningconditions, developing and selecting an appropriate support plan and operation scheme will improve theworking efficiency of equipment, increase labor productivity, and ensure workers' safety. This articleresearched a mining technology for the thin seams, focusing on coal seam 10T in Nam Khe Tam coalmine, 86 Coal Company. From the analysis of geo-mining conditions, the article developed and selecteda reasonable support plan and operation scheme for the face in coal seam 10T. After being used in thefield, the support plan and operation scheme have brought the face efficiency and safety.

Transfer and transition referrals of patients with intellectual disability from children's services to adult community learning disability teams

AimsThe audit aimed to assess if patients under the care of children's services in Wessex were transferred at the appropriate age and whether transition referrals to Community Learning Disability teams (CTLD) occurred timely. It also aimed to look at how many patients underwent transitions in a three month period, and if their transition support plan (TSP) was completed. A transition support plan should include chronological information on psychopharmacology, psychotherapy, and social support measures. Patients should be referred between the ages of 17–19 but require a justification after 18 years of age.MethodThe BI team was contacted to provide all IDs for patients referred within a three month period between the ages of 17–19. The BI team provided 42 patients with their ID. Patients discharged from services within a short time span were excluded for the following reason: inappropriate referral (9pts), discharged after 1st assessment (6pts), internal discussion (6pts), only referred to Autism team (4pts), moved out of area (1pts). From the initial 42 patients, 16 patients were analysed using the collection tool.Result4/16 had a TSP, and only two had a complete TSP and transitioned in another trust and were inter-team referrals.CAMHS services referred 1/16 patients.Psychotropic medication was prescribed to 12/16 prior to or on time of referral, but only two patients had a complete psychotropic medication history.8/16 patients' referral was commenced prior to their 18th birthday, and no information was provided for delay in transfer.Health records did mention psychotherapy, but apart from 2/16 TSP records, no additional information was available on the modality.ConclusionPatients with Intellectual Disability face challenges when transferring from children to adult services. Insufficient referral information may have a detrimental impact on patients wellbeing and long-term care.Access to a patient's chronological journey through the different children's services allows Adult CTLD health professionals to provide effective care. Historical psycho-social and pharmacological interventions provide a reference point for future interventions.Concerns included: limited information on most TSP regarding psycho-social and psychotropic treatments, lack of access to CAMHS/CHYPS paperwork and ineffective inter-trust communication for transition patients.This project highlighted the average number of transition cases in 3 months. It led to changes to the transition pathway, as awareness was raised in trust and CCG meetings to improve patient outcome. CTLD created the new role of transition facilitators to support children's services. They sit in meetings before patients transition referrals.

Direct Method for Solving Bilinear Programming Problem

The bilinear programming problem is considered, where a column, which corresponds to one of the variables, is not fixed but can be chosen from a convex set. This problem is known as the Dantzig – Wolfe problem. Earlier, a modified support method was proposed to solve the problem, using the decomposition of the problem constraints of the Dantzig – Wolfe method. The author of the paper has developed a direct exact method for solving the formulated problem. The method is based on the idea of the solving a linear programming problem with generalized direct constraints and a general concept of an adaptive solution method. The notions of support, support plan, optimal and suboptimal (e-optimal) plan are introduced which is a given approximation of the objective function to the optimal plan of the problem. Criteria for optimality and suboptimality of the support plan have been formulated and have been proved in the paper. The search for the optimal solution is based on the idea of maximizing the increment of the objective function. This approach allows more fully to take into account the main target and structure of the problem. Improving a support plan consists of two parts: replacing the plan and replacing the support. To find a suitable direction, a special derived problem is solved while taking into account the main constraints of the problem. The replacement of the support is based on the search for the optimal plan of the dual problem. The method leads to an optimal solution to the problem in a finite number of iterations (in the case of a non-degenerate value).
